Biggest tire on 1969 dart

best thing you can do is take a large square and measure your rearend from flange to inner fender lip. you can then measure the other way from flange to leaf spring side. allow 1 inch per side for tire sidewall clearence. the more the better but 8" wheel put it dead in the center of gap from leaf side to fender lip.

i had to use the offset 7/8" hangers and shackles. which i will be selling very soon all new
