I just used the stick on clips on my '71 Cheyenne. Not a big fan...They make the molding stick out a bit from the body so the the molding isn't flush.
Also after a day or two a couple of them came apart and caused an even bigger gap (of course). And I mean they separated from the part that clips to the molding. I'm contemplating removing them and drilling holes to cure the gaps and separation problems.
BTW-I used original not repro molding so it may not have been arrow straight.
