what size is the socket for the upper ball joint of a /6 1966 valiant

I think all the early A bodies with small ball joints use the same socket. They are a special socket & I think there are only three sockets used on all Mopars. I bought all 3 of mine from OTC tool. Depending upon the wear & tear, & rust issues on the upper A arms, they can be a real SOB to get out.
