There is a piece of black rubber/plastic that gets stapled (might be bolted on Fremont cars) to lip coming off the body to close the gap between the top of the rear bumper and the body.
Believe it is a 70 only part. I imagine many of them get tossed during disassembly. Pretty sure you could fabricate one, unless of course you are building a concourse car. Mine, I'm pretty sure had 5 small screws holding it on. Framingham built car. Jim Tapatalk User
70 only item.....basically bicycle inner tube rubber stapled to the flange. Not needed unless concours judging.
