My bad I was thinking about a 6.7 and they aren't available for the 6.4. I do know that it looks pretty damn good though and ADD makes a quality product. At one point they were having issues with the powder coat and I don't know if they ever resolved them but if I were to buy one I would get a bare one and have it powdered or bed limed locally so you don't have to worry about and damage in the shipping process.
