Ok,

The only thing left before completing my engine swap is the factory pulley bracket locations. I cannot figure out how to get the ac compressor back to where it should go. Is there any source that shows a schematic or breakout of what goes where? I'm stumped.

 

i dont know about the 87, it may be different. this is what my 89 GTA motor had on it when i got it.
looking at the front of the motor with the water pump at mid face, it had the smog pump at 7 o' clock, the ac compressor at 10 o' clock (with the idler arm to the upper right of the compressor) the alternator at 2 o' clock, and the steering pump at 4 o' clock. all the accessories were mounted to (2) cast aluminum supports. hope that helps!

 

That is exactly how the TPI ones went, but mine was the q-jet. I'm left over with a small bracket that doesn't seem to do anything, I know it does,but for now, I'm going to have to de-belt the ac just to keep moving on the rest of it. Thanks anyways.
