Throttle position sensor for R6 carbs

anyone know where I might lay my hands on one of these? Not actually for me but for a mate who has a car with r6 carbs...

thanks :)

Fowlers will have one or be able to get one.

ebay.......OR.....
if hes using a programmable ECU, youll be able to use any throttle potentiometer from any bike or car from the scrap yard (3wire if it has feedback facility).... just enter the values for 0 degrees and wide open throttle. (they all do 90 degrees)... ;-)
making it fit the throttle shaft wouldn't be no problem for someone who has fitted those carbs to that motor...
could be cheaper that finding one for an R6.........???
