The JB SYE was basically a bolt in application. I rebuilt the transfer case at the same time, so I put a little more effort into it, but it's not too bad.
The SYE and Ebrake were bolt on mods. I used a /forums/images/graemlins/hack.gif to make the slot for the rotor, them fabbed the cover, and installed it on the inside of the truck. The rotor only sticks thru about 3/4", and since I didn't want to do a body lift, this was the best thing I could think of at the time. One inch might do it, but you may want more room to allow for drivetrain/body movement when flexing the truck out offroad.
The ebrake works really well, and I am happy with the mods, the SYE and especially my 1 ton HAD CV shaft. /forums/images/graemlins/waytogo.gif
The only thing I would have done differently was to clock the 241 up before I ordered my HAD shafts. Still going to do it if $$$ allows.
