I only do them in stainless steel now and they cant be anodized, its not cheap to get one offs anodized, I did try a group buy on aluminium ones but there was not much interest. I don't do these as a business, I'm and engineer by profession so when I have made something custom for myself like these and bonnet mirrors etc, I just like to be able to give the opportunity to help others so you can understand why I'm not going to fork out a lot of my own money to be sat on a shelf. sorry guys that I cant help you out ultimately!
