Hello auto enthusiast, hope everyone is enjoying 2026! I'm trying to find the original part numbers for the outer window felt/belt sweeps for my '77 GP or a catalog that has all the factory numbers for the '77. Thank you all for your time for the help.

Wow, an SJ, with a 455?

That'* going to be a rare part to find.

I would think it would be the same as in a Monte Carlo, and you might be able to find those more easily.

Thanks CathedralCub for the reply, no it has the 400. They stopped the 455 in '75 I believe, and yes every part on that ride is hard to find. I have found the sweeps, I think, but have conflicting part #'* with the seller. I know there are part'* number books with cross reference numbers but can't find one. The parts are out-of-sight for the SJ, so just trying to be sure. Thanks again.

All org. but rims which I have, repaint, 76k m

Wow, that'* a nice one! I haven't seen one of those, nice or otherwise, in at least a decade!

I definitely understand the struggle to find parts for the low-production GM'*. I own a 1973 Buick Centurion 455.
