Stop in for a cup of coffee
I don't really know those trucks very well ....my only experience is I had a 70 but I ended up parting it out because the cab was really rusty. It came to me with a Arkansas title so I am sure it was from somewhere rusty. To my surprise, under the hood was a running 383 HP complete with the dual snorkel air cleaner. So I saved the engine and sold off some of the parts and the rest went to truck heaven.
Felt bad but I don't really need any more projects and I was too chicken to deal with the rust....especially when so many of those trucks are still around and can be had pretty cheap.
Would have been a cool tow rig though
