Sorry Drew, those are the ONLY chrome mouldings one DOESN'T have to remove during a vinyl roof replacement! All other pieces have to come off. Sorry I can't help you with those specific ones, but they all (I think) use the same basic plastic/metal slide-on pieces. Once you get the old ones off its easy to see how you need to re-install them. Some are "fed" and some are snappies.
