You will gain some strength up front with a 3/4 ton swap. The bearings and brakes are much larger than any 1/2 ton 10 bolt

Actually, the bearings are the same for 3/4 ton 10 bolt and 1/2 ton 10 bolt, only real strenght gain is in the 8 lug hub. Yes, the rotors are larger, but the calibers are the same so a little braking gain. Overall 3/4 ton and 1/2 ton 10 bolts are almost the same strength.
As far what is the best donor truck I would agree with getting a M1008 truck. So you get a D60 in the front and a 14 bolt in the rear, should already have 4.56 gearing and a detroit locker in the rear. Actually the truck it self would make a great truggy. /forums/images/graemlins/thumb.gif
