Wheel Hub 1970 Chevy Blazer

[mrucereto]

I know I am always posting questions... I hope one of these days to be able to read something and actually help you guys as well...

I discovered this weekend that one of my wheel hubs is bad. The knurled openings are worn and the lug studs won't seat correctly, if at all. A buddy wants me to weld the studs down, but the way the hub and the rotor sit together, I'd be welding the lug studs to the back of the rotor and have to break the weld if I ever have to change the rotor. I'd rather just get a new hub. (tonight I going to check and verify that it is the hub and not the knurl on the lug studs)

I have a Dana 44 front end that was converted to disc brakes. Of course I discovered this once I had everything back together and when to tighten the lug nuts and they just kept spinning and spinning... Below is my setup.

Does anyone know where I can grab one? I found what I need on RockAuto, but when I went to buy it, it said it was no longer available.
