Greg_H,
Just a note that your info on the ND "ball" bearings is correct for a 1-1/2 Ton, but applies to the 1946-50 model years as noted in the extract from the parts manual I included in a previous reply.
Design and bearing changed in 1951 to the "barrel roller" design and sourcing from Hyatt for original GM parts. Since Loren's truck is a 1952, his has the later style bearing.
Your stash of ND bearing sets will support all those vehicles listed in the parts catalog extract (see below) and hope you are able to rehome them as you indicated. Give me a shout as I may be able to help with that a little bit.
On to more info from Loren on finding and installing replacements.
Dan
