My dad got one from a friend of his, and was going to mate it to his '04 six speed. It's sitting on the shelf in the garage and has been for about 6 months now. The guys truck was a 98 12V 4x4 with 4:10s. I've been tempted to slap it on, but what needs to be done to put it on? I'm thinking the drive shaft, but what else?
