I have a 69 jeepster commando in which, someone swapped in An AMC 20 rear end with 331 gears (to match the Dana 27 - 331 ratio front axle) I need to get a new AMC 20 rear end, but i am having a hard time locating one with 331 gears (most run 354?) any ideas on which years, models, etc, i could find a 331 amc 20? I am looking for a short track model with a 'center pumpkin" (actually a little left of center)
any help is much appreciated.

lots of cherokees and wagoneers after 1980 used a AMC 20 rear with 3.31 gear ratio, one pc axles and heavy tubes...

a little too wide for you maybe though

Our 84 has 3:31 . It is a 84 cj-8. I'm sure cj-7 would have same thing.
Are you sure you could not rebuild it as cheep as replaceing it?

Most '81 and newer CJs with 6 cylinders came with 2.73s (std) or 3.31s (opt).
only '81s are narrow track models in CJ7-8s, '81-'83 CJ5s are narrow track also.
Hope this helps your search!

Can you get 3.54 gears for the Dana 27? Why not go that route?

what is wrong with the old axle? should just be able to fix that one.. mmm.. unless you bent or broke a tube or something..
can just get a housing and put in your r&p gears into that.. unless that is what is wrong.. then just get a r&p and put it in the old axle..
