I've got to differ with New69Owner. The rear end pictured is not refered to as a 10 bolt Corporate. There is a completely different axle that is a ten bolt and was used as a front axle on some of the earlier year trucks. Much much smaller and I think it was only used on half tons. I've found that refering to it as a Eaton or the HO72 is the best bet and eliminates confusion.
I had the same problem with my Eaton as New69 with my spiders. I found the inside splines worn and was getting the big "clunk" when put into gear. My 4.10 gears were in excellent shape just couldn't find spiders or axles. I did find some used ones but when I found a used 14 bolt locally for cheap..I jumped on it. Completely dismantled the 14 bolt and rebuilt it for a lot less than the parts of an Eaton. Got the larger 13" drums in the rear and now have a 3.73 rear with the option of lower gears if I want.
