Opinions needed on 72 to 75 D100 or W100 Dodge Truck

There's a reason the military and the Border patrol used Dodge 4x4s up until 1980. They were beat to sh*t and kept going. Front end included. The Ramchargers and Traildusters make for great rock rock crawlers. They get crappy gas mileage but they all did back then. And you can buy anything you need for them. Chrysler sold 100s of thousands of those things worldwide. If you look hard enough you may find one a 440 and a 4sp.
