The truck is in the body shop now. I'll have to take another look at it. The bed was squared and is equal distance from the sides to the frame in both the front and rear. The left fender is about 1/4 inch from the running board. We can solve that problem easily. The only thing I can think of is the fenders are out of wack. The running boards are new and measure the same. The running board braces are in the same position on both sides. Wierd for sure.
