A friend of mine bought this off of Ebay and wanted to share it with everyone. Pretty cool historical information of the car's development.

My version of the front brakes looks like this Disc 300mm Opel Astra-J GM 13502051 Caliper 2-piston 45mm Opel Antara / Chevrolet Equinox GM 96625936 - left GM 96625937 - right my version is on the left 1,5gen - on the right Use stock 16inch Wheel The mileage on this version is about 30,000 miles System without abs, stock master cylinder

Super stoked for this one! Just picked up this 93 tonight. One owner Michigan car! Not a spec of rust accept for around the windshield trim! Undercarriage looks virtually new! Has been sitting since 19, so some gremlins to work through! New top, but not a documented time of replacement. Has the usual oil leaks etc, and a horn / headlamp issue. But I am looking forward to getting acquainted with it! I think it’ll be a good pairing for my 95 as well.

It's been a while since I've logged in. I was more of a lurker back in those days... But I'm glad to see the forum is still up and operating!! Happy New Year Everyone!!

x2 on that, but, IMHO I wish they could have made the 2 doors with door handles in the door and not in the B-Pillar. These handles are nothing but headaches. And, the Verts would not have needed a basket handle (?) I'm needing to replace my LH Door handle. Again.

For once I condone a thread being resurrected 22 years after the fact.

It took me 22 years but I finally did do that manual swap

Here's a picture from back when the black car was in better days.

Well, from where I stand I would probably look for a 3400 LA1 shortblock, plunk the T-code heads & intake down onto it, & install a custom 3400 T-code engine into the car. I personally wouldn't waste my money on just a T code 3.1

All that work and I ended up dropping and breaking that vent awhile back. Thanks to an extremely generous member here I have a replacement vent. I keep the pair inside packed in a box so I can`t break them without effort. Had an idea and went with it in securing the drip pans and screens. Using some things I had on hand I came up with some brackets that can be removed easily for cleaning or paint. I don't know if it helped or not, but I also used a small wire brush to clean out the posts and put a few drops of silicone lube in them before barely snugging up the mounting screws. Everything holds tight and secure when the hood is open and closed and looks good from the top, underneath maybe different but each side is mirrored to the other to the 1/16" with the exact same parts. It could look better with fabbed up metal stock instead, but the idea works and can be covered with some insulation in the future. It really doesnt look half bad with just the screens and pans, and Ive not even painted those yet. Seems like it could match the front grilles...

My nephew and took her out last night and he's working on making content for the interwebz. A few of the better pics he took at the same place I took the convertible years ago. Unfortunately the P side rear caliper seized up and cooked the nearby rubber parts. That and most of the rear suspension is crispy from being up in Jersey so shes parked for now while the parts roll in.

It worked! Thanks for all the pointers. All I did was reflow the old solder so I left the rear deck cover off for now, the cover was very sun damaged anyway. But at least I have a working key fob now. IMG_7474.mov

Seven years later I finally got to it. Life gets in the way sometimes. It was a splice gone bad on the engine side, orange wire C461. DIC and scan data restored.

She dont look like much kid but she's got it where it counts...

Update. the 9.6121 pads work perfectly. I sprayed them down with silicone during install and not a peep or a squeak out of anything.

I have an f40 trans from an 07 g6 GT as well as a 2006 monte carlo lz9 3900 and will be doing a swap over this winter I will update with details as it goes along

That's OEM m'boy.....no muffler shop involved, the GT coupes that were fitted with the dual exhaust, & the STE's were fitted with that small left side muffler. It was done that way to get needed clearance under the floorpan, you notice that the left side floorpan has no heatshield in place to protect the fuel filler hose & the evap lines, but the right side does have a heatshield. That small muffler is fitted with a strap-on flimsy heat deflector that does literally nothing. If you toss the original rusted out mufflers don't toss the trumpets, keep them, those are near to the point of being unobtanium.

Also of note it looks like this car has the half pop up headlights that this clay model had as well, though it looks like they are taped shut possibly? Ignore the filename, definitely not from 1988.

The automotive news show motorweek holds marathons for their older seasons on Youtube and one of the episodes they played had this spy shot of a Grand Prix prototype that I haven't seen anywhere else. I wonder if they still have the picture in their archives.

For me, definitely the Black one. It being Black...and having Medium Slate Gray cloth, that is uber rare in the TGP World. You know me, rarity is a big deal and that one is definitely incredibly rare and sought after. I firmly believe that even though it's not in the better shape, you'll regret selling it later.

Got the knuckles swapped over and the GXP brakes installed. Going to tackle the e-brake next. Going with a rip-it style handle from an 04-ish J-body and a center console from an 00+ Monte. I have new rear e-brake cables from a 2G, so I'm going to need to figure out how to mate them with the Cavalier one. I know there's a thread somewhere on going to this style e-brake, but I can't find it. Anyone know where it is?

That's impressive for a MI car. It must have not have been driven in the winter.

Very interesting, you have both a rear sway bar and the auxiliary springs. I always thought it was one or the other. Very nice find!

Should be 2 or 3 bolts on the seat bottom facing the rear of the front seats. Remove the bottom seat cushion and then you will see the bolts that hold the back seat cushion on.

55 linked some w-body specific links. You may also check into the Fiero groups and see how their wiring is done and which PCM's they use. If you're on Facebook go to this group https://www.facebook.com/share/g/16TmFr1XSe/ They specialize in Fiero's, but he's posted a ton of info on wiring and PCM's. the concept will be the same, even if the wiring plugs to match the rest of the car harness don't line up.

Apparently It’s called a spring plate. If I’m seeing things correctly, it seems like it’s used to attach to lower part of a spring compressor.

If you care about originality and how the motor looks to be correct for a 1991 LQ1 car, you would want to stay within the 91-92 model year. You can use a 93 motor as well but the dipstick and tube is the only part that is a lot of work to swap over. 1991-1992 Lumina Z34, (standard with the LQ1). 1992 Lumina Euro 3.4, (standard with the LQ1). 1991-1992 Pontiac Grand Prix GTP, (standard with the LQ1). SE, GT, STE trim, (when optioned with the LQ1). 1991-1992 Cutlass Supreme coupe or sedan, (when optioned with the LQ1). ANY W body that has an X in the 8th place of the VIN will have the LQ1. Now...if you don't care about how correct the motor looks in the engine bay, you can go outside the 91-93 year range. The 94-95 motors will work but you would have to do some swapping over of parts to make it look correct. Some things are easy, some are not. The 96-97 LQ1's are dramatically different in appearance and functionality/engineering. They will get you more power but again, lots of internal and mechanical differences. These motors are also interference compared to the NON interference motors from 91-95. If you have any other questions, please ask us or you can PM me personally as I've gone in depth with these motors during my cars restoration efforts.

I can't really say. I've done it both ways from a fully functioning factory CD deck to a early 00's era 1.5 din Pioneer and period correct components. I see it both ways, sure pure stock is great and all but I kinda like when cars are a product of the time they were built in as well or even a homage to that time. I mean how many custom cars of that era still have original PS2s integrated into the dashboard As for your specific car, likely a member here would want to buy it and would probably want to continue or at least keep the vision you had for it. I say clean it up, and take some new pictures of it out and about, it was one of my favorite cars when I joined here back in 2004. Still is.

Well..... one doesn't want anything that is aluminized, at the very least 409 stainless, you might look thru Walker's Quiet-Flow SS series, their recent all stainless lineup may include something close to the original mufflers. Consider that you may end up going to a pair of 4 1/2x9 3/4" 14"shell mufflers.......the left side IS a 12" shorty while the right should be a 14", the right IS a 7x9 shell.

When I win the Mega Millions I'm going to produce replacement door handles that don't break. If you would like to support me in this endeavor of spending tons of money on lottery tickets please write me a check.

I honestly believe that you're *overthinking* this situation. these 2 are found on Amazon, the *781* is priced $8 more than the *761*. They cosmetically appear to be identical except for *what I see* the park return lever being a *new* item on the *761* vs a *used reman* item on the *781*, there were no piston dia changes '88 thru'93. As for ACDELCO themselves, I don't feel that they will supply you with an item that will outlast another rebuilders product & much of what ACDELCO supplies comes from Asia or possibly Mexico, I personally lean towards Cardone for my *reman* items. They are American. This leads me to my next question....what has happened to the current caliper other than a piston seizing up or a fluid leak that you feel it is necessary to replace it?

https://web.archive.org/web/20161019020737/http://www.rodneydickman.com/n36.html I did find that.

Same, I'd rather put that money down for brand new OEM style tailights.
