Hi, I have a 12 bolt olds diff with a broken axle. It is a 3:42 posi. I'd like to put it in my 68 olds cutlass, but need to replace the axles. Does anyone make this axle or does it need to be custom built? This is a 31 spline axle, seems to be a rare piece. TIA

 

I am guessing 'Moser'.

 

Check with Brian Trick. His user name on here is 507OLDS.

You are correct though. That is a rare piece and may be hard to locate.
