Celsior Ucf10/11 Rear Upper Balljoint

[Stain]

Recently bought a UCF11 Celsior and in the process of putting it thru RWC, etc... and one of the items are bushes and balljoints!
I've got all the bushes I need through SuperPro and I've fround new front lower balljoints on eBay and other random American online stores...
But my drama is the rear upper balljoints! That A-shaped arm... Part# 48770-50010 & 48790-50010

I can't fine replacements for sale anywhere! Does anyone know where to get them, if you can get them?
Can you press out the balljoint and replace it with a new-matching one? Does a suspension arm from another car fit? Soarer/Supra maybe?

I just want to exhaust all options before walking into my local Toyota/Lexus parts department and bending over the counter for em...

Any help would be apriciated.

Thanks
