The Fatman has one. Check out his catalog at
www.fatmanfab.com at the bottom center of page 10 is a pic of his. $65 a set.
I have a set that I have yet to install. They are the real deal, the tube must be 1/4" thick, I haven't mic'ed it but I can if you want to know or want some pics. Get it welded in and it isn't going anywhere.
