Help. I am working on piecing together a bunch of pieces to make 53 AD truck. The frame is a 3600 or 3/4 ton. I am going to shorten the frame to fit a 1/2 ton short bed. I finally got a used bed and a set of running boards which I am trial fitting to see how much to take off the frame and center the rear-end in the rear fender.

Not ever having taken one of these trucks apart or having an assembly manual (I know I need to buy one, but with my mix of parts I am pretty sure it would be less help than this forum) I need some help with the position of these parts.

The 1/2 ton running boards have three places for the carriage bolts to mount to three running board supports. My 3600 frame only has two supports on it, so I assume the 3/4 ton running boards are different. They are also apparently in a different place along the frame, since when I set the running board on the supports but pushed forward so that it is close to the front fender, the carriage bolts are about 1.5" in front of the supports. Are all three 1/2 ton supports the same ? I have another big bolt truck that I can rob a couple of supports from. I know the back of the running boards bolts to the front of the rear fender. How close does the running board get to the front fender ? How close is the filler panel that bolts to the top of the running board supposed to be to the back of the cab ? How much space is there supposed to be between the bed and the back of the cab ?
