what size pickle fork opening for ball joint replacement

[rjSupra]

Hi all:

I've been studying Mr Nickleye's excellent write up on ball joint replacement.

My question: of the pickle forks recommended, do I need both or either one? Would the 15/16" opening fork handle the job? (I can source that tool locally, the other 11/16" one not yet).

My lower ball joints on either side flunked inspection with 3/4" of play in each one. I found them at JC Whitney for $38 something each for just the lower ball joint which I was told includes the castle nut.
My car is an 1988 which has never been in the salt (except this winter now) with 130K. Not sure if there were ever done before, and i am hoping to be able to get them out without massive drama.

Sorry for probably a dumb question, but never done any suspension work before.

Thanks!
