hey guys, trying to find out what the best locker for a 12 bolt would be. I'm looking for something thats super tough, but not a too difficult to install. Anyway if any of you read my post about my tranny problems. Turns out the ol th350 is toast. I destroyed the gear that allows it to remain in park, and all the metal floating around did enough damage to require a rebuild. Oh well, 186,000 miles on one tranny isn't too bad. Thanks for the help. If in doubt, gun it.
