upper control arms w/o ball joint?

Weld the ball joints in the arms you have now and run them. It is done all the time. Use the search button on this site and look for yourself.

Im doing exactly what Okla said here, one side on the UCA has lousy threads, I've got the new bj in, just need to get it tacked in place. Tack it in 3 spots, that should hold it, then if you ever need to replace, just grind off the tack welds.
