Hi etnfrd67
are you talking about the wide U shaped notch on the top rear roof panel, where the vinyl meet's the metal? I think that is what you are after.
On my 28 coach I have a lead nail strip that forms to this wide U shape that meets to the vinyl, so I would think that your's would be the same, I have not seen any for sale in the 4 years that I have owned my car, so may be hard to find, maybe some one on the VCCA might have one for sale or might know where to find one.
Good luck on your search.
Keeping vintage Chevy alive.
