68 Cuda Upper ball joint removal - looking for help

Thanks for the suggestions. As it turns out, a set of sandblasted and primed UPCs popped up on Craigslist, a couple of towns over. So I bought those, and will just put the new BJs in there. Still will need the tool, but I saw on another thread that a spindle nut socket may work, and only costs $10 so I'm going to get one at O'Reillys and try that for tightening the new set up. As for the spindle, I smacked the knuckle at right angle to the BJ nut and it dropped right out - on the first try! Hopefully it will be just as easy to get it onto the new BJ nut. Looking forward to taking the old UPC off - hope it's not as bad as you say!
