Well the drive shaft needed to be shortened I went with 2 inches out i was told 1.5 to 2 with my configuration so that's at my local drive line guy being cut balanced and new u joints put in so that's good

Well had the drive shaft shortened 2 inches and fit perfect u joints were the same used same shockes I used the overloads and spacer from the donor truck and the u bolt plates I also had to get new u bolts made that were 16 inches long took 6 hours with riping the old axle apart not including part running vary straight forward swap also donor truck was a 01 3500 srw
