One thing is the rims are wrong . the other is those long shackles with those old bushings. You probably have rear shift . Here are the proper 8 in wheels with 275 60's . No rub small bolt BS is 4 1/4 on primered Duster and gold Demon , Big Bolt back space is 4 1/2 orange Duster. Narrow the rear or buy the wheels that fit.
