I wouldn’t worry about year just what ratio you want for what you want to do with it

Any similar year model with leaf springs. The older 12b's with the swing arms and coil springs will not have the proper brackets for your leafs. Aside from that, like said above, it's all about gear ratio.

If it has a 10bolt in it now, why change, you aren't gaining anything out of going to a 12bolt.
