HELP. Pressing Ball Joints Back In (Pictures added)

What year A body car are you working on anyway?
If your working on a 73-76 A body, and want to replace the upper control arms, i will be listing a pair for sale, tomorrow sometime.
Right now they are soaking in a pail of Evaporust, to bring them back to new metal looking condition.
PM me if you want.
