We are picking up a low pinion Dana 30 out of a TJ tomorrow for my roommate's MJ project. What I need to know is, were all years of the TJ D30 the same? Like when we go to get new u joints, ball joints, etc, does the year the axle came from matter, or can I just give them any random year of TJ to look up the parts for it?

Also, was there any front driveshaft length difference between LP and HP XJs? I've been told there was, and I've been told there wasnt, but I figured you guys would be able to tell me for sure.

Thanks
