The luck continues! Today I picked up a GM Corp 10-bolt front axle with 8-lug outers from an NP203 equipped 3/4 ton truck for $50! Everything spins over very well and it looks very good inside. Since this was originally on a full-time 4wd truck, there are no lock out hubs installed, rather a dust cap and a solid plug for connecting the hub to the axle. These will be nice to have once I do start wheeling this truck harder than I am now.
Here are some pictures: 
The only thing I was really hoping for out of this was that it would already have 4.10 gears. But as can be seen in the photos below, the ring gear states 41 11 so they are 3.73 gears… 
So this axle has the same gear ratio as my truck currently. Now I have the 8-lug outers to go with the 14-bolt full floating rear axle!
For another $20, I picked up a set of 15×10 8-lug rims. They need some good cleaning, but they are not too shabby for $20:
