62cutlassconvert, yes that is true with one piece drive line configuration, but a CV joint and center carrier bearing setup, things are set up differently. The first time I have any problems with my current set up, I will go to a one piece driveline. I have modified my upper control arms already, so the pinion angle can be easily changed as needed to get the driveline angles parallel. Having installed different rear springs (stiffer) and having the ride height one inch taller, the problem of the driveline hitting the body tunnel will not be a problem. That’s why the factory used the carrier bearing design in the first place, clearance issues.
