1970 duster slant six 8.25 rear swap

Large Bolt Pattern
5 on 4.5 instead of 5 on 4

Important to know, because you would hate to swap out the rear only to find out your wheels don't fit
Thanks, I got a question about wheels now I was planning on getting some magnum 500 wheels would a 15"x10" wheel fit on the rear of my 1970 duster?
