I don't know about the $100. But, on my l946 two ton, I took out the original Hyatt bearings and then went on the internet and found a cross reference page to Timken bearing numbers. The local Adance Auto store was able to get me the comparable Timkens. I had to replace both inners and outers because the Timkens were not of the same "barrel" Hyatt design. This is a real challenge. Good luck.
