I'm working on the driveshafts and need some advise. The rear one needs to be rebuilt. The length looks good after the lift, but the splines and yoke have serious wear and too much play. If I'm rebuilding anyhow, should I go 3/4 style? Would I need beefier t-case and pinoin yokes. Also, would a CV joint shaft be the best option and if so, what would it cost?
