Mystery Caliper Bracket

[pwmin]

Any idea what these could be from?  Custom strut housings for my Monte to fit GXP brakes, but the caliper bracket is not from a GXP and I have no information on it. Tim sent me everything he had, but it's not in there.  No clue who made these strut housings back in the day.  The Chevy dealer crossed it to a GXP bracket, but the bolt holes are about 8 1/4" apart instead of 5-ish for 2G W-bodies.  Small GMT800 brackets are too small but the larger ones are too big.  I have one on order from an SSR, which should be in between sizes, but I'm not sure.  It's a different Cardone number from either of the GMT800 ones, so hopefully it's different.  It doesn't look the same, but as long as the holes line up. Last picture is of GXP caliper and bracket.

Could be.  I will look into it.

 

I bought an SSR bracket and it's not correct, either.  It's in between the 2 GMT800 ones.  GMT900 won't work either.

The search continues.  Does not look like it will work to me.  I'll follow up on any leads I can get.

Reminds me of the caliper brackets on my Trailblazer.

There's two kinds at the front, which has two-piston calipers.  The calipers are the same, but the brackets are different between the regular-wheelbase Trailblazer (GMC Envoy, with Saab and Isuzu versions also.) and the extended-wheelbase Trailblazer and clones.  The extended-wheelbase vehicles got slightly larger rotors, so the bolt spacing on the brackets is a little different.

I tried SSR ones.  I think they're the same as the Trailblazer, but I'm not sure.  It was the closest yet, but still not correct.  Both of the holes on this bracket are 8 1/4 center to center.  They're directly in line and the front brace is straight across.  Not that that part really matters.  I'm going to look at the Cardone catalog and see what I can find.  I can ask them as well.  Last resort I might take them off and see if NAPA can match them up.  I did have my dad order GXP calipers with brackets from NAPA to his shop that I'm going to check out today, but I'm not very hopeful.  Figured I'd give it a shot.

I just figured it out!  Got the GXP brackets and calipers from NAPA.  They cut the mounting part off and drilled/tapped new mounting holes.
