Jim, that sounds like a fun time and a great day. It is always nice to see old friends. It is funny how they all get older; but you and I don't! Glad you had a really good time and found parts you needed.
Gary, I agree with you. However, many 70's cars and light trucks made in the US were pretty shabby. GM had some real quality problems and there automobile diesel was a disaster. I worked for a timber company and we had International Harvester 3/4 and one ton pickups, Ford F100's/F-150's, and F250's, Broncox as well as Chevrolet 1/2 ton and 3/4 ton pickups and Blazers. The best and most durable were the International Harvesters. However, getting parts timely was a problem. Every single Chevrolet pickup and Bllazer rusted out in the hood and tailgate in two years. The engines and drive trains were fine; the bodies were terrible. The Fords did well. A few rusted along the hood and tailgate; but not so they had to be repaired. The Broncos (the little Bronco) were great with no problems.
My dad had a late 70's Buick. GM used plastic between the bumper and the body. UV destroyed the plastic within three years. It crumbled away to nothing. I have not owned a GM product since although I know these problems have been long since corrected. Foisting junk off on the public left a bitter taste in my mouth.
