this D1 to fit 35x12.50's had to cut about 4" off. it broke the seal on the rear doors and would let water come in between the panels. so he fiberglassed it, when i go wheeling with him this weekend ill take some photos of it.
on my classic i only had to trim the front and rear of the front fender about 1" at the bottoms to fit 33" A/T's.
