Control arm question - Where the Sway bar connects - Part Name, where to order

[SubaruLegacyWagon]

I circled the part in green. I ordered adjustable rear control arms awhile ago to replace the old ones where one was bent. The adjustable one's I ordered didn't come with the attachment that let's me connect a sway bar.

Does anybody know if I can purchase this part separately instead of ordering a whole new set of lower control arms? Not sure what it's called.

Might go with a stock one that has the mount.  

Pretty easy to get.  www.car-part.com
