My 1971 Duster 6.1 Hemi build

Cool - Should fit anyway, I've got 275-35-18s on mine and probably didn't even need the offset shackles. The front is stock but with pan head bolts on the support and the fender braces pushed out in their original slots.
Pat, I’m going to try 18x10 24mm offset with the 255/40s, big spindles with Viper GEN II discs, QA 1 upper control arms. You’re thoughts?
