Plenty of clearance for the body pins in the rear. I re-enforce the inner rear fenders, outside the front fender vents with some tape. Also a little shoe goo in the above mentioned area where the cab meets the hood. For the most part the body has some weak area's like all SC body's made and the heaver the truck it is mounted on (4x4 SC) the more damage will come to the body in nasty crashes.

I believe the performance of the body will out weigh any cracking that happens.
