ive got a 6" lift on my 94 ctd 2500, ide like to rotate the t-case with an indexing ring.. but its a new thing to me! never installed one, is it a huge job? difficult? i would like for this double cardan joint to last longer than the last one when it exploded and cost me $430 bucks to get the back half of the driveshaft fixed!! plus it might ease up on my pinion angle on the front diff! thanks for any help guys!
