I talked to Johnny about EML and sports cats he said that he had seen information about this method of spacing out the second sensor cheers.. .
After reading a bit oubt it looks like this method works really well.
I had a look around and found this picture. Looks very similar to yours.
Picture taken from another forum (sure they wont mind)

Have you got a link to items on ebay for other members? or does anyone know where you buy these from in the UK?
