36hp distributor

I am currently rebuilding a 36hp engine with Wolfsburg West dual port engine kit, apparently I need to run a centrifugal advance only dizzy as the carbs have no provision for vacuum.
My question is where can i get one of these dizzy's? I have been searching the net & am unsure what ones will fit a 36hp engine? Is the shaft size different on later model engines?
The car it's going in is 12v if that helps?
Any advice would be greatly appreciated.
Cheers.

I may have one but won't be able to let you know for a couple of weeks. PM if you want me to look then

Look for a bosch 010 or 019

What carbs are they? Should be able to have them drilled for a vac port.

reason I say to continue using a vac carb is that it'll make the engine respond better, drive more smoothly and pull smoothly.

IMO small motors really aren't meant for mechanical dizzys. Heck they ain't no good for any street driven aircooled.

The dissys are off early Kombis

Thanks for your help guys.
