Here's one for you number dummy.
Front 3.50 data-aja
603482-3
Rear wfe-j 4cb
3l50 9 389a
Let me know?

 

Cannot be da, as the second digit of this prefix is a number.

Ford ID number: D4TA-AJA / Dana ID number: 603482-3 = Dana 44-7F Front Driving Axle / 3.50-1 / No Free Running Hubs or Limited Slip / 3,300 lb. Front Axle Capacity.

Ford rear axle ID tag: WFE-J = Ford 9" Rear Axle / 3.50-1 / Limited Slip / 31 Spline Axleshafts / 3,750 lb. Rear Axle Capacity.

4CB: Assembled the 2nd week (B) of March (C), 1974 (4).

3L50 = 3.50-1 w/Limited Slip / 9 = 9" Rear Axle / 389 = Production Code (FoMoCo usage only) / A = Assembly Plant.
