Im afraid i can't be of much help, but a mate of mine is well into mini's and he knows a guy who's the only person to bother seeing about dizzy curves. He does all the custom ones for the mini guys.

I can ask him for some details if you wanna get in touch n see if he can help you out? I know he's into mini's, but a dizzy is a dizzy and they're all made by similar companies and work in the same way.
