Got this 73 a few months ago, i paid for it before i drove it and he still lied about the engine, but i had planned to use a 04 gto engine anyway. It had ralley wheels so i ask what rear it had, he said 10 bolt, so i'm thinking maybe a s10 rear, nope redrilled 7.5 axles. It had an old bell like in 50's cars with mounts on the side and a cast iron 3 speed. Half of the tunnel was cut out on drivers side and patched with flashing metal like you buy a home depot, and the hole where the heater WAS, had a big hole cut out below the gas pedal and a piece of heavy cloth riveted over the hole. It had an hydraulic clutch, the master is made to mount at an angle so he had to a 3/4" stack of fender wshers to mount it, you could depress the clutch 2" at most and barley released. Got some pictures if i can load them.
Car was a 4 speed, and putting a turbo 350 in, need to know if the crossmember is supposed to be right for the 350.
