1965 Dana/Spicer 12 bolt posi carrier - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello all!
I'm normally on the '67 to '72 forum, but I wanted to post this here,because I felt somebody here could use these parts from a Dana/Spicer 12 bolt carrier.
I bought this off Craigslist,it was in a complete 1965 housing,had 3:73 gears, but they had really ben rust pits in a few of the teeth on both pinion and ring years, making them useless. I had no idea of the condition of the posi internals until I had disassembled it. After I used a GM door hinge spring compressor tool to remove the clutch springs, I found one of the side gears, the splined ones that drive the clutch plates had several badly chewed up teeth, and then I found one of the smaller spider gears had a tooth broken off, must have made its way though the other spider gears and ate up that one side gear. Once I got past the spider gears, I pulled the pressure plates out( the aluminum plates the springs compress the clutches/steels) I found those to be totally shot, I know I can get the clutches/steels, but I doubt I can find the spider gears. And I doubt the ones from a regular Eaton posi will work. By the way, these are 30 splines too.
I'm guessing even if I found the correct spider gear set, the cost involved with rebuilding this posi would exceed the price for a brand new Eaton posi carrier.
So, if anyone is looking to find pieces to restore their posi carrier, please let me know. Here are several pictures of the carrier and internal parts....enjoy!.
