Should be an #853 IIRC.
I had a glass shop replace my windshield about 5 years (?) ago. We reused the old gasket. Last year I removed and replaced my windshield myself to repair some rusty spots I missed the first time. Reused the gasket again. Reinstalled with the rope method and soapy spray and it was a snap.
3M #08509 bedding & glazing compound ,,, best stuff on earth. Will save ya a bunch of headaches.
Check youtube or the C10/Chevy Truck forums as the windshield install is basically the same.
