ive done a square drive line before i just wasent sure about sleeving and all. i just cut the tubing off the yokes so now i just have to find the right size tubing to fit over flange(not sure what its called) then have a shop weld it up. i would but it wouldnt end up being straight. not gonna go with the CV for now, if i have problems ill ad the CV later. thanx for all the help. any personal experiance with runin CVs in the rear or not would b great
