My 48 2 ton frame had clearly stenciled on the inside something to the effect of "don't cut or weld on frame"
You'll find similar notes on most all if not every big truck frame today.
The old frames may not have been as special a steel as we use today for truck frames, but that is not an excuse to do a less than professional job.
Hire a professional if necessary, someone that not only can, but actually knows how to properly repair truck frames.
Still curious about the original post, what's the reason you want a shorter frame?
