The repair really isn't that hard if you or a friend can weld. The process is to remove the steering box and any other obstacles first. Then you clean the area around the crack to remove the rust. Next you would grind the cracks a little to give you fresh metal to weld to. Then weld the cracks up. I would then grind the welds back fush to the frame. Next you would make what is called a fish plate out of 1/4" plate steel. The fish plate would be diamond shaped like this <>. The shape gives you the maximum area to weld to. Place a fish plate over each side of the frame that is cracked.
If the fish plates interfere with re-mounting the steering box, then you may have to drill them or opt for an aftermarket bracket that you can weld on to the frame. I think Currie and MORE make a stout aftermarket bracket.
This would probably be the quickest, easiest and cheapest solution.
how about strong? im less worried about quick and easy if it compromises strength, if it is going to break under moderate (as much as i can do without several thousand dollars of rock crawling mods) stress... also, since the crack is the better part of the area around the frame, am i going to have to worry about anything putting stress on the frame while cutting it and whatnot? again, my biggest concern is how strong is it going to be?i have heard when you weld onto a frame like that, the chances of the weld breaking under flex is moderate to pretty good... am i hearing rumors?
