Just had the door panels for my '70 Challenger re-dyed and am attempting to install the door sweeps. I suspect that both panels are '71 or later; anyhow, the reproduction sweeps I have will not press on far enough to lock in the groove at the top of the panels. The original, presumably factory sweeps lock right down but are not in usable condition.

Legendary shows two stock numbers, one for 1970 and one for 1971-74. Their tech support dept. is not responding, so I thought I'd raise the question.

Thanks for any help.
