Assemble a Dellorto 18.16 on Vespa 50s

Hi,

I have a Vespa 50s, and recently I bought a Dellorto 18.16. However this carburetor doesn't fit on my intake 16.16. I saw on sip-scootershop that this carburetor have a connection engine with 23,1mm what are the same size that a Dellorto 19.19.

 

So, my question is:

 

If i buy the this Bushing Intake Manifold

http://www.sip-scootershop.com/en/products/bushing+intake+manifold+for_11251700

 

and this intake 19.19

http://www.sip-scootershop.com/en/products/intake+manifold+for+shbc_15815000

 

it will fit on my Vespa 50s and I will can assemble the Dellorto 18.16 on my Vespa 50s?

 

Best regards,

André Barbosa.
