Window seals wipers weatherstripping

The window seals and window wipers on my 87 are all starting to fail, especially troubling is the one in the rear window which by now i am certain is admitting a little rainwater into the tailgate. The weatherstripping on my doors as well is all failing, coming up in chunks.

searched high, searched low, is all this stuff "cant get" anymore? help

Download their fullsize Chevy catalog. You can view it in section, so just get the weatherstripping section.

They have door glass weather strip kits, door glass run channels and door frame/opening weather strip for the 80s cars.

Edit, they also carry GM weather stripping for the 91-96 doors.

unobtainable

im starting to think this will require custom fabricoblication with some kind of standard foam rubber strip for window sealing
