Just in case someone needs this now or later...
In my new home town there was no AutoZone at the time (there is now), so I had to order a ball joint press. I got the SPX/OTC one. part number 7249. SPX/OTC 7249
thetoolwarehouse.net price of $86.92 was the lowest I could find with the exception of a couple of "scammers" that added really high shipping & handling charges.
The SPX/OTC is a really nice set.
The one AutoZone rents (OEM brand) is also good.
The one Harbor Freight sells has much fewer threads per inch on the screw and I have also seen a picture of a bent Harbor Freight ball joint press "c-frame" somewhere on the web, so I would avoid that one, expecially when quality tools can be borrowed for free or purchased for not that much more.
I also use the threaded rod, washers, short piece of exhaust pipe, socketes bushing installation/removal method. I have been doing it that way for so long that I actually prefer it over using a hydraulic press. At first I drill the old bushings and pull a part of it out with needle nose pliers.
When pressing bushings/outer sleeves in or out, I always use "c-clips" and "c-pipes" (c-pipe not needed on b-body LCAs) to keep the ars from getting bent. I make these out of 2" plumbing pipe.
CAUTION: Be very careful when sawing into an old outer bushing that is still in the control arm. On press fit parts it is almost impossible to see where the bushing ends and the control arm begins.
You don't have to saw all the way through the bushing. Just saw a little bit and then collapse it in with a hammer and a punch.
