Yeah, what Tug said. Don't order the shaft until the lift is on and everything is bolted in place. THAT INCLUDES THE NEW BELLY-UP SKIDPLATE whether you buy or fab one. That will change the height of the t-case and thus change the length of the driveshaft. The driveshaft should be the last thing to order because the measurement has to be exact.

ps. go for 35's... but only if you get the TJ flares AND a 1" body lift. Do the Daystar.
