I have sold sets of those before and gotten between $100-150. it always amazed me though. I could buy a junkyard axle for $100 and make more then that off just the hubs.
buy a complete axle from a junkyard. you will get spare axleshafts, maybe even flat tops if you find the right one. along with a couple dollars worth of scrap steel when you throw the housing away.
But if you are selling, PM me. I have parted several 8 lug 10 bolts and 44's. the only parts that people do not buy are the bolts holding the cover on and the tubes if I didn't sell the hosing complete.
