Output shaft play

Just recently noticed a very slight drive line vibration when taking off in 1st gear. Went under the Jeep and can feel that the output shaft has a little bit of up/down movement in the transfer case. Guessing that means its time for a SYE and CV shaft. I have a 4" lift that came with the 1" spacers to lower the NP231. Anyone know what size CV shaft I need? I know they extend, and will I need to change rear control arms?

You should measure and have a double cardan shaft built (locally or by one of bigger name places) to fit. You will need adjustable rear control arms to orient the rear pinion properly.

By the winter of 2014/15 I will be putting in my LT1 which I'm building up, I estimate it will easily be 350-400 horse. I'm curious if a super 35 kit will be strong enough, jeep is mostly street driven. If the D35 will not be enough and I have to go to a 8.8, will the SYE and Double Cardon shaft still work with an 8.8? I'd like to stick with the D35 if it will be strong enough as it already has new internals from when i changed gears to 4.56. Pretty sure the Vettes has a D44 rear end and ive read that a super35 is as strong as D44.
