We will mock it up but if I can get an idea to get me started I will be good Thanks for the help guys Josh

But the bottom front fender lip needs to be clipped/bent in a little. As the overall tire diameter increases room for the tire width will decrease.

In a wide front I have never seen anyone go bigger/taller than the 275/40-17 or 275/35-18 without running a fender flare. I remember seeing a Canadian autocross car with a 315/35-17 on all four corners with fender flares. You need to talk with Bill. I had a discussion with him once, I seem to remember that the track width was the same as my '75 K frame with Cordoba rotors. I also think that the Alter-K can not run as wide a wheel because of the steering arm on the spindle. Speak to Bill, he should know.

So you may need a little more back spacing on the wheel to get it to tuck in well enough to have clearance. (sorry - no a-body experience)
