Wanting to reseal back side glass.
I have looked on different sites and I don't see anything about a reseal kit.My seals are starting to
get brittle and I don't want any leaks.Any help would be much appreciated.
Give them a coat of black RTV (room temperature vulcanization rubber).
Try LMC truck website for Bronco 2 stuff, they have some exterior seals. I did what tenspeed suggested on my old Bronco 2 and my old Chrysler, I suggest using the ultra black RTV as it will closely match the faded color of the weatherstrip
Jeff's Bronco Graveyard looks like they may have what you're looking for if the recommendations above do not work (not discrediting them) or you are looking for additional alternatives: http://broncograveyard.com/bronco/c-359. I had a leak in the front lower windshield on my 1988 B-II, but the rear windows always treated me well. I was thinking of the weather-stripping that I had used between the bed & cap of my '81 S-10, but I don't think that would have worked. Good luck!!
