8" Rallye Wheels for 72 Duster?

I have 14x8.5 on the back of my Demon...I have 3.5" of BS though. I can't see 4.5" working unless you move your springs in. Here's a couple of pics with only 3.5" of BS and you can see how close the tires are to the springs...another whole inch of BS would never fit my car. You might get away with it with 255's though...I have M/T L60-14s (equates to 275-60).
