What I noticed on my '72 Duster was that the 3/4" rear offset shackles helped with the rear spring section, but not at the front. Obvious if you think about it, but I didn't do that work. Needed front mount to be inboard, but I'm not sure what's available there. 275/60R15s on 8.5" rims (4.5" BS) were still tight at the front section. Oddly, my '74 with 8" factory Rallyes & 275s cleared the springs fine at both sections with a .250" spacer. Never rubbed. Moved spring eye back .250". My '70 is like Cab's deal; springs moved to the rails & mini-tubbed & stretched a bit (just cut), so a 13x31 slick fits fine on a 15x12 rim. There’s a front and back part to the offset kit. I have heard of guys just doing the back but that doesn’t make sense to me

I run Dr. Diff's offset kit on my Duster and a MT 28x10.50 slick is not an issue nor is a 275/65 MT Drag Radial on a 10" rim. I am pretty sure my offset is 3.75" on both sets of wheels. I run a Weld Wheel with the slicks and a Torque Thrust on the radials. I'm not sure if the later model Dusters have a little more space in the wheel well from the early years, as mine is a '75. I did have to shim the hanger to center the tire in the wheel well (front to back).

All you need is the correct offset shackle and front hanger kit, no reason to chop up the car, imop. Plenty of room, my uncle has this exact setup on his duster. Runs a 275 pro m/t at the track and a 275 on a 15x10 on the street. Thanks ! this is the info I'm looking for
