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

So my left control arm striped when removing the old ball joint and I'm looking for a brand new complete arm and can't find anything. They're all over ebay for everything but an A-body. Even the rare parts one that I did find no one has including rare parts themselves. I have a new set of Hotchkis arms that I'm thinking of throwing on there but I'd have to ream out the knuckle and I had planned on selling them for my car painting fund. If anyone knows who sells a new complete arm or has a left arm ready to go please let me know. Thanks!
