Another really good source I've used for 20 years is Bob Selzam in Toms River New Jersey. His business is called 'Half ton fun'. Just Ford trucks and almost always NOS. He has tons of big truck stuff too and answers his phone. I have had great sucess with Joblot and they always had a great catalogue, which Bob didn't. Fun tidbit, when I needed front wheel bearings for my 38 tonner, years back, Joblot told me a very popular carnival ride (tilt a whirl?) had used those hubs and bought out all their stock! They probably bought all Bob's too.
