Thanks for posting this! I've been looking into this harness bar and I'm very interested in picking one up.
I didn't know that they released it yet...their website still shows it as coming soon:

Where'd you purchase it at and how much if you don't mind me asking? Also, can this be used with the stock rear seats still installed?
Thanks!
