Yeah...just follow the directions. Marlin sent me directions to install a dual t-case adapter with my 4.7's. Didn't get me very far. So I made about 100 trips back and forth in the house to glance at the online instructions, what a freakin joke huh. I did the 23 spline set so I had to pull my adapter anyways and put the new large coupler in to accept the 23 spline stuff. Online instructions are awesome. You do need to get a gooood set of snap ring pliers too. It all came with brand new seals and gaskets. I didn't get the sweet MC shift knob though, no big deal. You can do the whole swap in one day. With the case sitting on the bench and in 4-low...i can turn the input with my thumb and 2 fingers. That's some deep gearing.
