From what i've been reading you need a dial indicator. Needs to be no more then 5-7 degree's off.. anything more then that and its going to start screwing things up.
I'm probably going to lengthen my rear CV driveline and integrate the 14 bolt end on it.
The front's going to be tricky because I dont have much space between the upper link and where the driveline will be, especially when its flexed out.
