You can use the motor mounts from a 78-79 Grand Prix that came with a 301, maybe even latter, I don't know when they stopped using them. The transmissions that will work are, Turbo 350, 200 4R, 3 speed manual, 4 speed manual. Manual transmissions are rare, they stopped using them in the early 80s, you can buy the pedals and linkage on Ebay sometimes. The rear ends are 7.5s, some of the Monte Carlo SS and Turbo Buicks used a 8.5 10 bolt. High Performance suspension pieces are easy to get. You can use the front springs from a 3rd generation F body or a S10. The front sway bar from a 3rd generation Z28 works, the front sway bar from a WS6 Firebird won't work because it's too big. The rear sway bar from a 64-72 A body is the same as the 78-87 G body. You can find rear sway bars on some Oldsmobiles.
