Just a shout out for Chuck and "Truck Haven" (Unionville, TN...just outside of Shelbyville). Visited today and took the nickle tour. Basically a small hobby/retiree parts yard, clean and fairly well organized. About a dozen 67-72 C10 trucks in various states of disrepair (two small window 67's) and several sheds of 'stuff': lots of OEM sheet metal, engine parts, etc, etc.
Chuck is about as nice as you can get, knowledgable and helpful.
I scored a pair of bench seat-tracks (the handle on mine is broken off) and a nice, clean Q-jet for rebuilding this winter.
I tried to talk Miz Diane into buying his set of Buddy-Buckets but she likes the bench seats (frankly, I do too...so no big deal). Price there wasn't all that good...but he was also not terribly keen on selling them.
Great thing about the trip is that he had a truck sitting out which had the 2/4 drop. Miz Diane took one look and said, "I like it. Get it done on ours."
He also had a clean rolling-frame in the yard that I used to show Miz Diane about frame and undercarriage parts. She's not a car-person, so it really helped her to see the basic parts out in the open.
I'll go back in a heartbeat. Can't beat dealing with pleasant folks!
