Does a seal exist for my factory 1977 c10 sliding window
I just pulled this seal out of my 1977 C10 Silverado. I'm 95% certain it was the factory because it's so beat-up and had the matching aged chrome lock strip. I've been finding mixed answers on what is the best solution for this fix. I don't have a preference whether it has the Chrome locking...- 77Big10

Passing CA Smog help - High HCs
I have a 1977 GMC 5.7L 350 given to me from my dad. It passed smog no problem less than a year ago for the title transfer.

Newbie Alert
Just purchased 77 C10 Scottsdale. Wanting to lower it not slam it. Currently sits 31" in front & 31.5" in the rear. This measurement is at bottom of wheel well. Is it possible to do a 4/4 drop since it sits even now. Not wanting to do any notching of the frame. If so what's best way to go. Thanks.- Dallas Detherage
