Disassembly of my 92 968 Cab for restore and repaint and ran across something not in the manual of the PET.

Looks like a black caulk type material was used to fill in some of the gaps for the rear trim - maybe something similar to windshield caulk? Simple foam rubber material was used as well. Finally, some form of a putty based tape was used to seal around bolt holes.

Anyone know what these items are, or better yet - a source part number for replacements?
