Re: auto to manual swap
Measure with a tape measure, from the air cleaner stud to each fender to see if the engine is offset. If it is close to on center (same measurement) They are small block mounts. If your measurements are 1" different, you have big block stands.
You may be able to cure the problem with a big block z-bar and a frame mounted ball stud.
