Offset Shackles and Hangers

Early b-body 8 3/4 rear and offset the springs/hangers .80". If they are really 6.5" backspace, you're going to need a good bit of spacer.

We used 17x9 on this car, early b-body rear, springs in .80", backspace is 5.94 on cobra r wheel we used, no spacer:

I have a 68 barracuda in storage (have not had time to try/fit big wheels), but I'm assuming it's a bit closer than the duster out back. With the 8 inch wheel, and a 245 tire, it should fit no problem. 8)
