I have a 1972 cutlass S and Im taking out my Oldsmobile motor and dropping a chevy 468 in it and I was just wondering which motor mounts I need? can I use the Oldsmobile mounts or do I need a different kind? if so which mounts do I need?

Welcome to the site. You need to treat it like a Chevelle, use Chevy engine mounts and frame brackets. You also will need to run an adapter plate or a non-bop transmission. Starter wiring needs to be moved to the other side and possibly other accessories may need to be rerouted.

Here is an engine mount/ frame bracket kit:

Good news, my 72 frame was already drilled for the chevy frame mounts, yours almost certainly is too. Just buy 72 Chevelle.
See post 172 here for the Chevelle mounts.
