Since I have been assembling my 1952 3100, I have been wondering if I have the wheelbase as precisely at 116" as the specs call for. I have measured it a number of ways but I decided to wait (before I ordered a new drive shaft) until I put the bed on to see how the rear wheels fit within the femder on the bed. Well, as I test fitted the bed onto the frame, I noticed that the top (highest) bolt hole for the fender seemed to be directly over the center line of the rear axle housing.
Does anyone know if that is a correct assumption... that dropping a blumb from the center of that top hole should point to the center of the axle housing? If so, I will stop obsessing and measure for the drive shaft.
