Finally getting to disassembling my doors and noticed my guide channels have a plastic strip on the top that guides the glass (up/down), one broken off and the other is cracked (see pictures.
Replacement guides look to come with a FELT (whiskers) pad on them instead of plastic. (I noticed a post on 68's have the whiskers type) and I see just the "Whisker Strip" available aftermarket. (NPD calls them: WINDOWFELTS, Door Window Rear Guide repro, 222A58-1A)
I have used doors in addition to the original doors that are this early, plastic type. The question remains if theay are not cracked too.
I am wondering, since I already need to place an order, if there is a way or recommendation of repairs that others have already done. I don't see any point in buying the whole channels but wonder what others suggest.
