This has pics and a YouTube video. From the N2uitive site.
I think you can ignore the part in the video about the locking pins, looks like the set pictured about is the new RSX-3 version, which they don’t officially advertise on the site. They snap in just like the OEM plastic links that come with the car, instead of using a safety pin (kind of what a grenade would use), which is from the old version.
