Upper ball joints

Can you purchase upper ball joints seperately (from the UCA)?

I changed out my complete UCAs on my 95 and 97.......but I have a friend with more time and less money and he would rather press out the old ball joints and press in new ones if the option is available.

If anyone knows part numbers that would be great.

It hard to determine a list like this exists because there are soooooo many post about front end suspension replacement.

Thanks for the help,

Ron
