hey just wondering what if any driveshatfs are longer then a stock xj front shaft with an aw4 4.0 , i am in need of a longer one for my rear a stock one is about two inches to short . I was thinking about a tj or newer xj with a l.p might be a little longer anyone know , I have a stock shaft in the rear now and it bolts up but it is at the very end of the travel .
