I cannot tell you where they are located but the company is called RARE PARTS - I think in Tenn. My neighbor found them and was able to get a NOS .010" oversize kingpin set for my 46 2 ton. It's my understanding that Rare Parts is pretty much NOS stuff. Also try Bob Adler of Adler's Antiques in NY (he's on the web) - He writes articles for Vintage Truck and has answered several questions for me. He has a lot of info on Art Deco trucks.
