First off, we always like to see pictures.
Secondly, welcome to the 'bolt!
The wheels should be Motor wheels with a lock ring, not the split rim type, but I could be wrong. On the trucks I have sitting around my yard, they have 7.5 x 20s with an overall height of about 36". That seems to be about standard.
Im going through the same thing right now on mine. I have a few of them apart and derusting in my electrolysis tank at the moment. Just so you know, those 5 lug rims are pretty hard to find.
