Where can I find the side back window trim for a 90 B2. The rubber is too hard to reuse and I need to replace the seal. Before I pull the windows I need to find the trim so it can be replaced. Any insight would be much appreciated. Windows are leaking from the sides and going to the front corners of my headliner, looking to fix ASAP.

 

I don't see the rear side window seals listed in the LMC truck catalog , no wonder the PO of my 87 has what looks like gorilla glue up there !

Have you tried your local Ford dealer or Dennis carpenter ?
