tod in mid 70's gm mounts changed and as far as i know then on they are the same i may be wrong but i pulled motor in from 82 chevy truck dropped into 84 pontiac and the motor came out of 76 malibu only time mounts came off block was to put the 4x4 braces in behind them and take back off

As I said,I can only speak about what I know and that is the 68-72 stuff. Also I thought he was talking about the frame mounts not the ones on the block.

all 80s are the same frame mounts just diifferent bolt locations
