Likely 12" drum with the square pattern retainers on the axles.

I removed them from a Currie rear HP 9 in a YJ to do a rear disc conversion with new housing ends. They are 31 spline and 5 on 4.5 bolt circles. They are not the big bearing Torino ends, so they don't use set 20 bearings.

So Cal pick up only, 2 drums, 2 axles complete with bearings and retainers, slightly rusty from the salt air.

Currie axles. Too good to toss, too oddball to sell.
