Toyota Front Brake upgrade

Since the 89-95 Toyota spindle is becoming so commonly used on other minitrucks as well as toyotas, Just wondering if anyone would be interested in upgrading the front brakes?

I have upgraded mine to a 12"x 1.25", I was thinking about producing and selling the conversion.

Who would be interested and what would you pay?

I'd be interested. Don't know whats its worth. What are the rotors off of?
