46Sparky,
The reproduction floor board was the correct dimension and fit in the cab fine. The problems were that the master cylinder access hole was in the wrong location (approximately 1.5 inches off but still okay "as is"), the battery access slot was 1.5 inches too far towards the front, and the floor perimeter brake bends were very inconsistent in their depth from one side to the other. My original floor had consistent channel bend depths of 0.50 inches on the 3 sides that should be bent, whereas the reproduction floor varied from 0.50 to 0.75 inches. Nothing fatal, but just needed more work than I thought it should given the price. As I stated before, if I were to do it again, I would just fabricate my own.
