GS VS2T

Hello!

I want to purchase this item...

http://www.sip-scootershop.com/EN/Products/50501900/Speedometer+for+Vespa+150+GS.aspx

....but i also need to buy the speedometer cable and the speedometer drive gear, and this is where i need help.

 

Can you please help me find the compatible cable and drive gear for this speedometer?

I have a last question. As i have to replace the ignition coil and the light coil, is it possible to buy two equal light coils? Or the two light coils are different?

 

Thanks! :)
