I marked where the holes were and then punched them with a leather punch and didn't use any sealer my 63wagon only had the clips it wasn't glued down
I did mine the same way, except I put a strip of masking tape over the holes on the body . popped the hole locations threw the tape , removed the tape, stuck the tape to the weather strip and transfered the hole locations. Was a lot easier than measuring all of them.I marked where the holes were and then punched them with a leather punch and didn't use any sealer my 63wagon only had the clips it wasn't glued down
