Wendell, I had a 71, and 72, back a few years ago and both were good trucks. One of them was a work truck and the other more of a leisure type daily driver. I ran'em hard and they held up well.
Just a thought....as you may already know, not everyone stops in here at the welcome centre every time they come visit. I'm just saying this as you may want to ask some questions... how/what/when/where type questions in the garage forums. It will get you more interaction, and knowledge, than you can see here.
The AD years, with the "slatted" grille is a popular model and parts are available. They boo-coo's of them so many parts are re-popped and many can be gotten from individual members by posting in the Swap Meet Forums.
....be sure to also watch for other members that are close to you. Believe me, Stovebolters are everywhere, which is a good thing. Good luck on your pursuits.
