I've been in brief contact with a guy who formerly made these for FJ Cruisers. Because of a combination of limited demand and potential liability, he is NOT selling them any more. He gave me a couple of pics (I don't currently have permission to share; I asked) that make me think that the one pic above that we've been bandying about is his work.
Now, Jerry from BAMF is very busy and doesn't have time to design these from scratch. But I think if we give him a design and perhaps pay a little extra denero up front for some time on the mock up and tooling, he still might be able to come through for us.
So if you think you'd be serious about laying down - say - $250 plus your existing sway bar as a core - post up on that thread in the BAMF forum to let him know you're interested and serious. And that's just a number I pulled straight out of my ass. So don't give him or me any sh*t later if it turns out to be a totally off base number, OK?
