why is it impossible to find new small ball joint a-body complete control arms

I'm in the process of replacing mine with a set from QA1. The old ones could use new balljoint, but I think the bushings looked decent, at least on the driver side one I've removed. If you want them, make me an offer and I could pull the passenger side one off during the week and send them out. They are off a 72 Duster.
