I just recently bought a Trac Loc for my 8.25 Rear Axle. I'm looking for gears now but my buddy told me while I have the rear end apart I should go ahead and upgrade to an aluminum Driveshaft. Besides the junkyards Where can I find one? And if I do go the jy do need to find a 2wd reg cab since that's what mine is and it has the 42RE. Thanks!
