Missing Pulley?

ART_Auto

Hey everyone.

After discovering the epic belt slip that is happening on the car i was doing some searching for bits and bobs and came across this picture:



if you look closely between the supercharger pulley and idler to the left there is a small idler wheel in the middle which would create a bigger contact area on the supercharger pulley reducing belt slip.

Does anyone have this idler wheel in their kit? Does anyone know what the wheel part number is or what car it comes from?

I saw the threaded hole yesterday and thought nothing of it until i found this image. If I can get hold of the idler wheel i will be fitting it.
