Does anyone sell and extender that has flanges on both sides?
Bolt the extender to the rear of transfer (or front if that's your problem), then bolt driveshaft to extender...
Seem's like an easier solution than redoing the driveshaft..........
It is easier but then you end up with longer bolts that bolt the driveline to the flanges. The longer the bolt the easier it is to shear off. The right way is to lengthen the driveline
