Before you get to far into spending $$$ take a look at the pics and then plan what you need to get the pinion angle correct. It can be done with or withou shims, T-case drops and MMLs. All depends on how she sits after the lift and you go to line up the shaft take a look at the pinion angle. Once you have that figured out you are good to go. and then how to get to the pinion angle you need. I inserted both the standard two joint (stock) shaft and a double cardan shaft for the SYE install.
