Small Ball Joint Socket

What options are out there for the small ball joints? Is the only option the one from PST? Or is there a parts store rental piece that'll work on the smaller size? I used a crescent wrench and one of the legs from a hoist to get the old BJs off, but I want to make sure I get the new ones torqued to spec, which isn't going to happen with that setup.

Just tighten them down Tight, as you can.
Don't worry about it, don't loose any sleep over it.
Yes, the proper socket works wonders, and makes the job easier.
