Upper and Lower Ball Joint Replacement
I've always understood that there are two sizes for the upper ball joint socket - one for A bodies through 1972, and the other for B bodies and 73-up A bodies (at least the ones with the four and one half inch bolt circle). I have never worked on a C body, so don't know what they would use.
For the pre-73 A bodies, that holds for 9 and 10 inch drums and disc brakes, all of which use the same upper control arm. Anyway, I have two different sizes. From flat to flat, one is approximately 1 7/8 inches (measured with a tape measure, so that's an approximate measure) and the other two inches.
Note that an A body ball joint fits a bit loosely even in the smaller socket. It will work, however.
