Shorten a long box?

I've heard of it being done but what's involved? Are the wheel bases the same on the short and long trucks?

114" vs 122"

I can be done but will require tremendous rework of the sheet metal and sourcing of new end stampings for a short bed.

Roger Carter is gaining momentum as a positive member of FTE.
To keep the factory proportions the bed needs to be shortened between the cab and rear axle and behind the rear axle.

Keeping the body line straight (as factory) is where the work is. Several different approaches, depending on who is doing the work.
As Garbz mentioned, the rear bed corners are different between a long and short Uni.

And then you can start dealing with the torque box...

It is a lot of work and really not a project a novice should attempt.

I have a 62 uni long box. It was a project a buddy started. He took some out of the rear to shorten it up. Finished it off nicely, and it looks fine back there. Might not be the same as a real short box in the back but it looks good. I was thinking that I could move just the wheel opening cut outs forward and move the rear up to match the wheel base of a true short bed.

I looked at it a bunch though and I'm actually fine with its looks. Because it has the bed attached to the cab it doesn't look bad like a lot of detached long box trucks Ive seen that the same treatment has been done to. Its a rust free truck and Ive never really looked that closely underneath to see this torque box thing.

Its not really a truck for this forum though. Has a Volare front clip and a 350/350 Chev. I believe this site is for more "pure" Ford enthusiasts. I know I joined awhile back when I had a 78 Ford 3/4 ton ... very helpful place.
