John A Simpson John couple of notes. CWI sell a 30 spline chrome moly stub shaft you may want to look into. They are rated for 600 hp. The stock ones are rated at 450hp. You may want to look at a locker for the rear also. You didnot say what you are going to do with the car? Street, 1/4 mile, autocross, roadracing. A Jag rear is a basic Dana 44 case. Alot of parts internal, are interchangable with Jeep parts. I did my own, with the strongest parts I could find. Get an gridle for the rear caps of the rear. Make sure you have a breather for this, because it gets hot and the
oil will blow out the seals or tube if not there. 1/2 shafts same thing with chrome moly. Good luck Rick Lake
