bet your going to have to go custom. Another option is to powder coat the ones you have. As cool as that dually is, one of the drawbacks is the rims and tires. If iot was me the powder coat would be the best option price wise and looks wise.
89yotadually: I have a set of 4 that I had sandblasted a few years ago and painted with zinc rich primer and then silver paint. They currently have low mileage load range D tires on them too. Send me a PM with an offer. They are currently on a former 86 motor-home that I am parting out due to terminal frame rust.
