Randy, sorry, I didn't see the post all the way down here. By the way, thanks for posting to others questions while I was gone, I appriciate it. I can check to see if I can have a set of the 15x8's machined in 4-100 for you. I have never had the request yet, so I am not sure, but it will not hurt to ask.I'll see what I can do thanks Aaron 800.428.8355 x395
