As far as frames and axles go: gm only made 3 4x4 frames for these trucks:Blazer,shortbed,longbed. There is no difference in half or 3/4 longbed frames. The differences for those two are in the the springs and axles. The long bed frame is a bit beefier than the blazer and shortbed frame. If it is indeed a shorty you need to figure out if it's a long bed chopped down or a true shorty frame. If it's a chopped longbed, as long as the welds and prep/finish work (frame notch, and fishplate) are satisfactory I'd drive the wheels off of it and never look back. What axles are under it? D44 would be a stock front axle with a Dana 60 or Eaton ho52 being stock rear for a 3/4 ton and a cooperate 12 bolt would be stock 1/2 ton.
