22's Tucked

In order to get 22s with stock inners to tuck on a static dropped (5/7) shitbox, how much do the fenders need to be widened or axle narrowed? What is the most cost effective method?
Thanks all....

I think you can just swap your rear end for a c&c rearend. Maybe someone can correct me if im wrong.

DZL1.

c&c wont fit with stock leafs, 3" wider on the fenders is what I was going to do (each side). Have not tryed it but I think srw rearend will work for what you want. someone may correct me on it though
