I've asked him a question to see what the center hole diameter is. I'm guessing it is 5.25", which would be 54 and later, in which case they will only work for the last two years he listed (without making bushings)... sure won't work for a 38 without bushings.
Now if they have a 4.75" center hole that would be very odd and unusual, as they would have been new replacement wheels made in the mid 50's and later for use only on pre 54 trucks.

Sure does sound like a lot of money, then figure shipping on top of that, and once you get them you would likely sand blast and paint or powdercoat.. throw in some new tires and they could cost a few times the value of the truck you put them on.
Usually when I see them for sale the price is a whole lot less than he is asking, but I don't see them for sale very frequently.
