I measured a TriFive chassis today to determine wheelbase. I measured from the center of the front wheel to the center of the backwheel, and did this on the left and right side to get two measures. The wheelbase of a TriFive chevy is supposed to be 115". What difference would you expect to see and how much difference would indicate a damaged frame? Is 1/2" difference from side to side a real issue or will that come out in the alignment??
