8 3/4 housing studs- Axle tubes & chunk

Does anyone know where I could buy these in bulk? Like a box of 50 or so each? Axle end studs that hold the backing plates and axles are different than the ones that hold the carrier in, and I need both. I know Dr. Diff, Mancini, and a few other places sell little kits, but I would rather buy enough to do several rearends. I've Googled until my computer shot me a bird :finga: and NO LUCK! Any ideas on a source appreciated. :prayer:
