replacing upper control arm

That's the number i would believe it to be.

I have found a bit more information in my Chrysler Muscle Car Parts Interchange Manual 1968-1974.

1974 drum application isn't the same as 1972 back so there is a modification. 1973 is the same on both drum and disc.

1972 back upper control arm part numbers with applications.
