Really, none. You may be able to use 3.8 frame mounts, but afaik you'll need to make your own blockside mounts, or get some A body frame mounts and motor mounts, set the engine and trans in so its aligned front to back, and weld em in. Few guys on here have 455 Buick cars, maybe they'll chime in.

You need to use 68-72 Skylark chassis mounts, the engone sides are the same. They wont line up with any holes in the frame so you'll have to drill your own. TA Performance and Summit sells them new if you cant locate a used set.
