Compatible vehicles for engine?

I have a 1999 K1500 4wd 3 door pickup early body style with a 5.7 crate
engine that was put in about 60k miles ago. Over the winter, I went into a
ditch backwards on the ice and bent the frame at the rear (the hitch is bent
90 degrees down (trapping the spare)). The body shop has told me that they
can't straighten it, essentially rendering the truck worthless. What year and
model pickups are compatible with this engine?
