Good idea. I looked around online and measured the new OE right unit once it arrived. 14mm x1.5 thread coming in from the inner tie rod, 12 x 1.25 going into the hub.

By crawling the 555 parts listings, and ebay, I'm guessing 555 Sankei SE-t021L & se-t021R may work. These are parts to fit the 05-11 Yaris and others, one OE Toyota part that comes up similar is 45047-59135.

I found a se-t021r on ebay for $26, so I'm ordering that to compare side by side with the new OE unit I got from Subaru. I also have a replacement steering rack off my car that I can play with/test fit.

I'll post my findings once the part arrives.
