I think the thread size on the spindle nut is 2 in 16 but I could very likely be way off. I'll check some more.
As for the brakes. I tried an olde school trick and cleaned the pads with brake cleaner then heated the surface with a torch. That tends to bring the oil to the surface a bit and while I doubt they are cleaned thoroughly that might suffice for the short term at least until I can find a reliner.
