It comes from the factory on 2001 Grand Cherokees, don't know if all or just some. I don't think anyone else is doing it as the Valeo site only mentions the Jeep as an initial application. I am just about certain its not going to be an off-the-shelf
after market mod anytime soon. More likely a raid-the-junk-yard-scratch-head-fab-brackets-start-over-refab-stuff-test-modify-scratch-head kind of mod.
