Upper Ball Joint Tool

Maybe I'll see of the parts store has a loaner. I can't see buying a special tool for a single use.:(
Since the UCA is out of the car, I don't think I have to worry about clearance...hence, I don't think I need to squatty profile. If I had a 1 7/8" standard socket, that should work shouldn't it?
Nope. The ball joints have rounded corers between the flats. Like the shape of the socket. I have seen guys use Crescents and pipe wrenches. Nope. Not the proper tool.
