Roto Track Arm?

A home owner says:
December 13, 2016
I'm looking for a replacement arm that can attach to a roto track. I've already replaced the inner track parts, but also need to replace the outer track. I see the outer track and the track slider (links below), but I don't see anything like the single arm that attaches to the window per the photo (it's the brass-colored arm, not the silver-colored one)

Any ideas?

Thanks!
