Frame stretching?
 

Many seem to be experts on shortening, but how about lengthening? I ask this because the only longer than 8 foot beds you can find on modern trucks (1973 to present, I use the term modern loosely.) are chassis cabs which require a CDL to drive, and are hard to get rid of, for that reason. Other than changing drive shaft, wiring, brake lines etc., what do I have to do to make a truck longer? Thanks.

the 63-72 had a longhorn that was 8 and half foot bed if i remember right.Like said you cut the frame to make it longer weld in pieces and same goes for the bed.Every limo you see on the road was done this way,Or you ever seen a 6 door pickup same way.

Thanks guys. It does not look like a difficult concept. Is it better to make a straight cut or a diagonal cut?

The frame 'stretching' I've seen usually has a long support brace.
After you've added the amount needed for the stretch, add an extra support piece,
Good luck

I think the question of "just how long are you talking?" has to enter in here somewhere. There is a reason that the heavier/longer trucks have a taller, double, thicker, ect. frame. A few inches is one thing, but a few feet...I think you should think & plan carefully. Especially if you plan to use this "as a truck". My Two Cents, Lorne
