That just depends on how expensive the donor truck is. You can do it piece mill, but thats going to be expensive in the end. Your better off buying a cheap donor truck, get what you need and sell the rest.

Gotta do something about front and rear hangers, If you wanna go the easy route find a 4x4 frame or maybe parts truck.

Second thing you need either a 2" body lift (i hate body lifts) or swap in the high hump from the before-mentioned parts truck and your good to go.

Remember, 73-80 and 81-87 frames are different.
