The Stovebolt Site Forums The Shop Area Driveline Jeep axle?

Looks like it will be okay, but is the pumpkin offset to the right or is that just the image? If you find a Chevy C10 pickup from the mid to late 60s (maybe early 70s), they're the right width and have the proper 6 lug hubs. Also the parking brake scheme can be adapted to the AD setup really easily. They'll be drum brakes. These will be the GM 12 bolt rear end and parts are very available and in some cases very affordable. Some ring and pinion sets are $150 or so...which is dang cheap. A few weeks ago I posted a link to the GM codes (so you can easily tell what ratio these are...stamped on the upper passenger side of the axle tube). The stamped code assumes nobody has changed anything inside which is usually correct. Here is something else to keep in mind...I don't know what transmission and rear you're hoping for but in the 12 bolt rear end there are carrier breaks that limit the range of ring/pinion altering you can do. It all has to do with deck heights inside the rear end. For the 12 bolt truck rear they are: 2 series (2.73 and down), 3 series (2.76 to 3.42) and 4 series (3.73 and up). If you get a passenger car rear (won't have the 6 lug hub) the deck heights are slightly different so the range is: 2 series (2.76 and down), 3 series (2.76 to 3.73) and 4 series (3.90 and up).

So in my case, my rear end (a 2 series from a 1969 C10) has a 3.07 ratio and I could change that to a 3.42 if I wanted to...and there are spacers that will allow you to use 4 series gears in a 3 series carrier.
