Thanks Clay - that’s part of the greatness of this forum is sharing the information - wish I’d known it before dropping $450 or so for a steel driveshaft behind the 4L60 in my ‘68. I’m trying to take a lot of photos and share part numbers in the same way - maybe it’ll help someone in the future.

I may be hosed with the engine mounts. The summit slider mounts don’t slide as far forward, meaning the towers will need to be further back. The ones I bought (same as my ‘68 which I loved being tubular, easy to route things around etc) fit nicely in the front location, but when I slide them back they don’t sit flush at all with the crossmember.

I’ll mock it up but have a feeling I’ll need another style motor mount
