I will be ordering a CV driveshatft shortly and I want to get this all correct. Once it is installed to dial in the right pinion angle I need to do what to the upper and lower control arms. I looked and to me it seems...1.) I have to lengthen the uppers to push the diff back to line it up with the transfer case. Thus shortening the lowers as it rolls back. But then again I could argue that...2.) shortening the uppers will pull it up at the angle needed thus lengthening the lowers. The second seems more likely but this is my first lift that required a CV. Please help!
