I have a 76 350 from my cutlass that I am trying to put into my 1980 LeMans (G-body, same as malibu and 78+ cutlass). I thought the frame mounts from the 76 would fit but it seems they may be different. All the pictures I have seen of frame mounts for these cars have one mounting hole in the center on the top. Mine have 2 on each corner and one offset in the middle (on the top). Wondering if anyone has any experience with this car/motor combo and could help out. Thanks.

 

The 1973-77 A-body cars are completely different from the 1978-88 A/G body cars, so no the mounts from the early one will not work. You need the frame mounts from any 1978-88 A/G body or any 1977-90 B-body with an Olds motor. Note that those mounts are subtly different from side-to-side, so be sure you get them installed properly. Use Anchor P/N 2328 motor mounts (same on both sides).

And FYI, the 1978-81 cars are technically A-bodies. It wasn't until the FWD A-body cars came out in 1982 (think Olds Cutlass Ciera and the like) that the RWD cars became G-body cars.
