Crank Pulley Help

[Norton]

Hi All, and before you say it, this is not another thread asking "How do I remove the crank pulley".

I am looking at installing a supercharger (USA Kit) but I am stuck with how to run the additional crank pulley.

It looks like my crank pulley and crank position thingy is one complete unit? How do I remove the single crank pully and bolt in a double one (One for Acc. and one for supercharger). Like this one: http://store.summitracing.com/largei...fa018021_w.jpg

Any assistance would be appreciated.
