Time to Buy Tires for the Duster......help please.

Many people say the Duster wheelwells are the same as 2nd gen Barracudas.
IDK. But 295/50-15s on 10s fit in my 68 Barracuda with ease, even lowered quite a bit. With a bit of massaging on the inner side, I even hung a pair of 325/50-15s on 10s in there. So yes the wells are generous.
Moving the springs is a couple of hours work,no biggie..
After that,you can narrow the rear to run a standard 4.5 backspace. You need a minimum of 1/8 to the springs, and a minimum of 3/8 to the closest part of the inner. The metal moves with a BFH,no problem. I run 24psi to get proper tread life. Yeah it rolls over in the rear around the corners, but you get used to it right quick, and then it just becomes rear steer. The roll is minimized when the tires are spinning. Also the clearance is increased when spinning or the faster you go,lol. I have run tighter than 1/8 and 3/8,at the track.
