Got my axle shafts swapped today, the K1500 is assembled and driveable.
The Treasure Yard axle has some damage I'm not thrilled with. Turns out to be less of a "score" than I'd hoped; but still saved me having to buy an axle shaft for the K1500. One axle shaft has some pitting on the bearing area, but the seal area is fine. The other shaft was great, is now in the K1500. The pitted shaft from the K1500 is now in the Treasure Yard axle; so both shafts are now compromised. They'd both be usable in a pinch, but certainly not optimum.

There's major wear on the spider gears, which I totally did not expect. The side gears seem to be not affected by the torn-up spiders. 'Course, that all goes away if I put a locking differential in this core at some point.

Brake shoes and drums are "OK". Drums should be turned, but not horrible. Shoes have lots of material left. Adjusters aren't seized.

3.73 ring and pinion look beautiful. Put the thing back together, using the original grease for rust prevention; locked the brake drums on with the lug nuts. Sealed up "for later".
