Jim, the bearing numbers cross over as follows;
Ford BB 4222 is Timken 3920
Ford BB 4221B is Timken 3984
Those are the inner hub bearing. and the diff side bearing.
The outer hub bearings are:
Ford BB1240A is Timken 462
BB1239A is Timken 453X
The inner hub seal is a BB1175C Timken make these under part number 5751S (it appears to be National 5751)
War time Chev no. is GM 1798517 (they fit many of the F15, C15 and larger CMP trucks)
If no joy with Ajays, or Nigel, Then try the Chap in Hervey Bay, Australia. (Sorry, I have forgotten his name)
If you want to go further, Macs Auto in the USA. There are many options.
If you are in no hurry, it might work out cheaper to import the whole lot.
I just searched a ford bearing and pulled this from a web site "MIBearingsLLC"
