That's a daunting swap! Wish I had the balls to do it, but I draw the line at cutting away at a unibody frame that likely wouldn't have won any 1995 IIHS safety awards in the first place. You're all good BCM-wise, there isn't one.

Yep, I've probably removed the bezel a hundred times across 3 Cutlass Supremes and it's never broken. It's hard plastic and seems brittle, but it's actually quite durable.

That's your only option. Once those screws are out, you have to pull that bezel towards you as it's held on with tension clips. The clips are metal and won't break. I've never had a problem with the bezel breaking either. It will sound like it's going to break...creaking and moaning, but it will come. Also, I just disconnect the connector for the headlamps switch, I don't remove it from the bezel. With the bezel out, you'll see two 7 mm screws I think they are that holds the radio to the main dash. They will be at the bottom of the radio. The radio will slide out and give you some room to disconnect the connectors from the back of it. Disregard the dash pad being off. It's not necessary to remove the pad when just removing the radio.

figured id do a how to thread. this how to will directly apply to 96-99 1st gen ws. will apply to 88-95 ws if doing complete obd2 swap at same time(some parts the 4t65 swap parts list are shared with the obd2 swap parts list). wondering why 4t65 swap? several reasons. newest interchangeable 4t60 was made in 1999, newest 4t65, 2002 so a lil more jy available. after i did the swap shifts seemed more solid and crisp(along with the knowledge that my lil 3400 would never kill it lol). if ur planning an l67 swap but are a brokeass (like me) it alows you to do half the swap at a time and when you actually get around to dropping in the 3800 its just an engine swap period. also the required pcm for the swap has the same gears as a 4t65hd programmed in it. PARTS LIST -4t65(duh) if you dont wanna do any programming get one with 2.93s ie 2000-01 lumina or 97-02 l67 anything -2000-01 lumina engine harness, also need plug from donor where harness plugs into drivers side underhood harness -2000-01 lumina pcm(still pk2 so no security issues) -97-99 z34, 98-99 ltz, or 2000-01 lumina trans cooling lines -if using non hd you can use cvs from 97-99 z34, 98-99 ltz, or 2000-01 lumina 98-99 monte, 98-01 lumina pcm tray is handy but not required but handy if using hd trans you can use the same d side cv as above but on pass side get the inner cv cup and swap onto your cars stock pass side cv another note if using hd trans-you MUST use a torque converter from an l36/l26 or 3x00 or it wont bolt to flywheel
