Upper Control Arm ( UCA ) ball joints

I would like to know if the upper control arm ( service part ) ball joints for the early Falcons with part numbers C2OZ-3049-C (RHS) & D (LHS) are the same and / or can interchanged with the later ball joints ( used again in the Falcon as well as the Cougar, Mustang and Maverick ) with part number C7OZ-3049-A. Both the 1962 version and the 1967 are the 4-bolt style, and visually look the same.
When I looked in the MPC, it would appear that the early Falcons were also listed for the C7OZ version, which is what leads me to believe that they are interchangeable ?
Any insight or help in this regard would be most appreciated !

No idea if your theory is true but I have used the 1965 - 66 Mustang aftermarket ball joints to restore an original 1965 Falcon upper control arm. Not sure if the upper control arm itself may be the same part number as Mustang.
