OK, here's an updated list, I have the one that's a 1 in. rubber part # 4802102 I think came from somewhere in the Firewall, that is also not in the set. I think I have all of the originals, but some of them were out of the car before I started working on it. They were in a box in the trunk with some other misc. parts. What I can remember;
1 - 1 inch Rubber part #4802102 goes in Firewall in unused speedo-cable hole.(not in set) I have !
2 - 1/2 in. plastic in top of cowl (not in set) I have !
2 - 3/4 in. rubber, 1 in each Rocker Panel brace behind Kick Panel
4 - 3/4 in. plastic, 2 in each rear Outer Wheelhouse (front and back)
4 - 1 in. plastic, 2 in each Trunk Floor drop-off
2 - 3/4 in. plastic, 1 ea. side under back seat
does this look complete?
