Re: 75 GMC sierra classic face lift and conversion to short bed

Good starting point. Where overseas is it? And forgive me for asking, but why not just find one closer to home?

There are several ways to go about cutting the frame, 1st measure 6" off the rear cab mounts, you'll be removing 14" of material, I like an interlocking fit, so I measure 20" with 3" top and bottom interlocks, think the z shaped pieces in tetris. Brace it with angle iron and clamps. Measure a bunch of times to make sure its square and tack it together. Set the bed on to make sure your wheels are centered, pull it back off and finish weld. Then fish plate. You'll also be removing about 6" off the end of the frame.

Others may have different ways of doing this, but I've done it this way on three of my friends trucks and came out golden.
