I'm looking for a fresh set of spider gears for a gm/eaton HO72 axle out of a 65 C30, does anyone have experience finding these other than in the junkyard?
 
The Eaton HO series has not been manufactured in around 40 years. Junkyard is really your only option for HO parts, but they are still easy enough to find. You can also swap out the spider gears for 14-bolt parts and run the outer shafts off of a 14-bolt, which would be the better option.
 
I may have a Detroit locker that fits an Eaton... It goes in a split carrier, like a 14 bolt, but it's larger than a 14 bolt locker and the 4 shafts are smaller. It has coarse splines...like 19 or so? I've been having a hell of a time figuring out what it's for. It was sold to me as a 14 bolt locker, but it's definitely not. However, 14 bolt side gears will fit in it.

How much you looking to get for it?
 
I believe that's what I measured. I can check it again if I need to, it's out in my shop.
