Spindle Bolt Markings

I've just found two sets of used spindle bolts that were buried in the bottom of a box of spares & one set is marked with an A near the Ford script & the other set with a B. Are these for the model A & B respectively as their measurements seem to be identical, & were they interchangeable between the earlier & later models.
Thanx
