need quick answer
since I'm replacing my solid aluminum body mounts (on a 71) to new polyurethane mounts from Energy Suspensions, will I need longer bolts? Or will the stock body mount bolts work?

I would like to replace my discs with a neoprene disc that is identical in size to the aluminium discs. It might have to be slightly higher to allow for compression when the body is on.

IMO - You are gonna need new (longer) bolts.
Here are a few pics to convince you:
Aluminum thickness:

Poly thickness:

I don't recall the length of the originals in the 70, but you
will need 3" or so for the poly mounts.
Looking at #1 in the pictures above, the sandwiched poly would
originally be the 3/8" aluminum puck. Under the bracket, there
were a couple of washers - that's it. So, the difference in overall
length is over an inch. Expect the body to sit about 1/2-5/8"
higher off of the frame than previously. Definitely a good mod -
looking at the corroded aluminum that I pulled.
