Weber Query

I have just replaced my Zeniths on my Euro 1973 911T with some refurbished Webers 40IDA 3C's.

The engine is fitted with a Bosch distributor with vacuum advance which connected to the Zenith carbs.

The Webers do not have a vacuum connection. Should i drill a hole in each manifold or remove the vacuum from the distributor ?

Many thanks

I spoke with someone today who mentioned I could fit a Bosch distributor from a 911s which has no vacuum advance.

What would you recommend?

Personally, I would have the distributor recurved and run w/o vacuum advance.
