BTW - there were alignment issues with some Dodge vans around that time. My '77 B200 required alignment different from published alignment specifications. Otherwise, it'd eat tires.
If you notice unusual tire wear, do like I did and find a very knowledgeable alignment person ... someone who can align from scratch rather than just following published specifications.
But first, make sure front bearings are up to snuff and preloaded correctly. Also, check ball joints/kingpins first.
If your tires are wearing in the inner side of the tread, check your brake pads. If the pads are wearing in a taper rather than uniformly, your front bearings weren't preloaded correctly.
