8.8 swap

My Duster, inner fender lip to inner fender lip measures 68".
The 8.8 is 59.5 disc to disc ( 2 3/8 wider than the 8 3/4 drum to drum).
That gives 4 1/4" from disc to inner fender lip on each side if your car measures the same.
If you want the tires to tuck under I think the rim should be about 2 inches inside the lip. (This is my guess, can anyone verify?)
So the rim should be no more than about 2 1/4" outside the disc.

This 17x8 bullitt rim has 5.7" backspace so 2.3" outside the disc.
Could be OK but I don't know if 4" of offset compared to the normal 1 1/2" would cause vibration or cause the d-shaft to hit the tunnel.
