I did modify the mount some and grind a bit off the frame around the clutch area, but the compressor fits inside the frame. I added some steel to the parts I cut to make them stronger. Get some fuel tanks from a 1987 truck (they have the fuel pump in the tank) and upgrade the pump. I think most of the guys are using the Corvette type fuel filter with the internal regulator. Use the stock radiator with Camaro fans. The passenger side Exhaust manafold will need to be modifyed if you use the f-body manafold. Nelson Performance sells the wiring harness. Allen can also tune and remove VATS and other unused bits from the ECM.
