Converting my 87 GTA from V-belts to Serpentine using March Performance Pulleys. I know I could go to the junkyard but I want the Billet Aluminum stuff to increase the aesthetics of the engine compartment.

 

GTA,

My '86 has a plain shaft - no key, no knurl, no spline. Just press it off and on. I'm almost certain the '91 with the poly 'V' belt that I had apart included the same sheave/shaft arrangement, so I would guess that the '87 would be the same.

One note about the aluminum sheaves - they look pretty but wear out faster. If you don't drive daily, it should be fine.

I'm planning to drive it a whole lot and not just have it parked in the driveway. I just don't want to look around for too many miscellaneous parts and brackets. The thing is my GTA does not have A/C, or A.I.R. pump. I bought the 1LE A/c delete conversion with different Power steering and and waterpump but need the other stuff. I know I'm going to go nuts trying to make this happen. Maybe someone with the Camaro Parts and ilustration Catalog can't tell me what part number would I need as far as brackets and bolts to convert from 87 to an 88 up serpentine setup without turning the A/C compressor or Smog pump. Please help.
