I need the ring and pinion for a 12 bolt but would consider whole rear end .I live near St. Louis . Prefer some thing local but I'll consider other options. I would like to have a locker also. Email me at drka@charter.net

I have a brand new set of 3.42 gears(12 bolt) that I bought off of ebay and never used. $110 shipped to your door. I am going with a 4.11 instead so I won't need these. I take paypal too.

I have a clean used set of the factory 3.40 ratio 12 bolt gears, Since this is a ratio that I use I like having a set around, but I am buying airmales entire 10 bolt when he's ready so I'll let this set go for $40 plus ride. the splines on the yoke end of the pinion gear got slightly flattened and can either be filed or toucked with a dremmel type whizzer wheel. this makes no differnce in the strength its just that the pinion yokes won't start on until thye are fixed. It's not rocket science and if i had a loose yoke here I could fix em up. lemmeknow, DAVE
