Does anyone have suggestions on where to have my ring and pinions upgraded? I'm running 31" Mud Rovers on my near stock 86 4Runner, and need to go to at least 4.56 gears if not 4.88's. I want to put an EZ/Aussie/Lockrite locker in the rear at the same time. Before I tracked down someoen myself, I wanted to see if anyone had recommendations in my area. I live in Northeast GA.

TIA
