Hey Bob, I checked for the number and found a 26 stamped in the backing plate. I took the drum off and didn't find any number on the spindle side. On the outside bearing is the following: Ford B-1216 Timken X, if that helps any. Like I said, the axle assembly has the spring mount forward of the axle instead of above the axle like on the A. However, instead of the wide bolt pattern of the 39, this has a 5.5" bolt pattern. It also had 16" wheels on it.
Hope this helps, again, thanks for your help!
