I read recently that Eaton is now manufacturing their posi carrier's with a new type of clutches that last longer. So, you might be able to buy one that fits right without having to search.

Truck and car 12 bolts are different.

Have you looked on e-bay? Try searching for '12 bolt posi', you'll be surprised what you find from shim packs, ring and pinions all the way to completely rebuilt 12 bolts with heavy duty axels and c-clip elminators.
