73 Duster rear fitment

On my 74 Duster, with the 7.25" rearend, I have AR Torq Thrusts all around.
Rear-
VN105D Series Torq-Thrust D Wheel Size: 15" x 8"
Part Number : 286-VN10558065
245/60/15 Tires

Front-
VN105D Series Torq-Thrust D Wheel Size: 15" x 6"
Part Number : 286-VN1055665
215/60/15 Tires (I think)

The 245's on the rear are TIGHT. The passenger side tire would rub the pinch seam on the inner wheel well, and was only about a 1/4" from the leaf spring on either side. I hammered the pinch seam a little bit on the passenger side, and am using a really thin, 5mm I think, spacer. Fitment is great now. Not sure how different the 8.25" is compared to the 7.25" fitment wise. You can also get spacers in the thickness you need, but 275 might be a little too tight. You'd probably be better off with 245's or 255's unless you're tubbed or have offset leaf springs.
