    Here is the truck pulled into my friends shop for dismanteling. Took 4 hours to pull the front sheet metal, winch, engine, and trans.

            14 Bolt done


            Redoing the rear suspension. The rear shackle hangers are modified GM units. The frame was plated and bolted to hold the springs. Overbuilt may be a common thread in this build.

                  Seats are GSS "cobra" seats. From an MRAP (Mine Resistant Ambush Protected) military vehicle. They are comfy and have an intergrated 5 point harness already!

                        After about 9 times of adjusting shims, it was time to paint some teeth and check the meshing pattern of the teeth.

                          And here is the final backlash! Everthing was well within spec. I must say regearing a differential is not hard, just time consuming and very detailed! Dont be afraid if you have the tools!
