OK, lets help him out a little bit.
You ahve two choices for 3/4 ton and 1 ton front ends for these years. It's the Dana 50 TTB and Dana 60 front end. The dana 50 has a lot more moving parts, and camber changes with load. This is OK for a vehicle that is a commuter vehicle and occasional towing, but a vehicle that sees a lot of change in weight on the front axle will wear tires out quickly. Also, bushings and the moving parts are difficult to change. The dana 60 is expensive, but a stronger axle, and due to the solid part, the camber is fixed.
You want the 1356 case, it's the common one.
It will be cheaper to buy another truck. Two weeks ago I bought a 1995 F250 4x4 for $2300. It's got the 460, but is in OK shape. The cost of parts for this will get very close to what your vehicle is worth plus the extra parts, or it may cost more. You can get a great deal on vehicles when you don't need one. Some people really need to sell.
