Up late? hell its early! Funny thing is that Shawn and i were talking about this subject tonight, he is really happy with his drivelines and has 0 complaints. He had them done at 6 states, if there is one close Id recommend them.
With a flat belly you end up raising the case(s) up to the level of the bottom of the frame. Its actually a pretty cool deal, but I havent gotten the truck to my standards enough to go on the trail and enjoy it.
