With the changes made to your truck, I would suggest you physically bolt a wheel on that you know the actual measurements of & work from there.

You should be able to put a truck ralley (steel wheel) on & take some measurements where things are relative (suspension vs. sheetmetal). Add an inch here or there to arrive @ what works for your combo. I use stuff like pieces of wood taped to the wheek/tire to determine additional clearances required.

FnLow69, Where you at in Washington? I have a set of 20's that are the 9.5" wheels. I will find out the back spacing on them. If your close we can throw one on to see how they fit.
