Hi all, Has anybody used a Spartan locker on rear only with with a 247 trans. case? ( 2002 Grand V8 I.R. 2 inch 31 inch A/T3W ) I emailed Spartan and they said it was ok as long as i don't use a front locker. What has been your experience with this set up. I know it's the best " BANG " for the buck tick tick.
