I've been asking around for about 2 years now. I've contacted everyone from Callaham to Hipshot to hobbyist machinists and no one's got an answer for me. One like this but a couple inches wider to fit a wider pickup. Anyone?
it wouldn't be hard with the right tools. even without the right tools, a person could cut one down the middle and weld in more metal, grind the welds and replate it.
You could even make one yourself if you have the material, a hacksaw, files, and a vice and then get it plated.
Go to a custom bike/car garage (the kind you see on american choppers/pimp my ride) they would probably knock out one for peanuts (if you ask very nicely).
