Looking for a 71 Dodge Dart Chrome Side Trim?

Through '71, they attached with clips that went through holes in the body. I doubt you want to drill holes in the body, at least I hope not. Starting in '72, it was affixed with glue, so no holes. I'm sorry I don't remember where to find the generic stuff, but you can get something very similar to original in rolls to put on there with adhesive.

If it were me, I'd leave it as is. I understand you like the trim though. That's a beautiful Dart. Is that black with black top and black interior. OMG, holy crap, that's really a nice car!
