I agree with Rene, cutting that truck would just be sad, move the axle forward, and if you do end up cutting do yourself a favor and cut a very small amount at a time. You can usually trim just enough to clear but not really make the outside of the fender look any different.
Redrilling the perches and stuff is super easy though and you wouldn't have to trim, cause you know trimming a truck that clean will kill 10 kittens and 10 puppys.............................................................just sayin
