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.
