Jim--I think the FA57 was the one that used the RA15 pumpkin in a front
axle in 1600's and the FA58 was the wider Dana 70F that was used in 1600's.
Believe you are correct that FA52 is the unit for 1300's and 1500's.

In any case, the knuckles and spindles were the _SAME_  on all three of
them. Hubs, drums, lug pattern, and backing plate assemblies varied.
