I have two sets of axles for the 9.3" Olds/Pontiac rear used from 57-64. Both sets are 31 spline stock axles. One set is from a 59 Bonneville and are 31-11/16" long from tip of axle to the wheel mounting surface. The other set is 30-1/16" long from tip to wheel mount surface and according to Dutchman is from a 57 Olds. Asking $100 per set. Both look good just need cleaned up a little. Bearings are still on both sets. Also have a few other stock 29 spline axles for these rears. What do you need.

I was thinking 57-58 Olds had a different number of splines than 59-64. Where are you located ? PM coming.
