Had these parts for a while, the conduits I have had from the 80's never used them, there are no part numbers but they are GM ( worked for them for 11 years ) I think I ordred them for a B body but I am not sure what year they are ( the ones for my 69 A were NLA so I tried these, too big for my door holes approx. 2.5 " on one end and approx. 2.25" on the other). The other piece is a reverse back drive rod that was suppose to fit my 69 Beaumont but it is way too long so I figured that it must also be for a B body ( it measures approx. 20" long ). If any one is interested in these parts let me know.
