Yea I got that all figured in today. I used 72bluNblu's set up as a guide and my total outside/outside tire width will be about
1/4-1/2" narrower than his and since I'll be using 285s and he has 295s my tires inside/inside are a little wider than his. So a 9.5" rim with 6.35" BS and a 285 tire should bolt up to an uncut 8.8 and fit perfectly in a Duster!! I'll know for sure in a few...years :( LOL
