Manifolds with vacuüm tubes Z1000J

Hello Guys, having a question.
I bought some mikuni smootbores 34 mm. I was working to mount them, but there are no connections for vacuüm meters on the, so i cant synchro them.
My manifolds (Z1000j) dont have them either. I seen that older Z models have manifolds with vacuüm tubes, but i understand that these wont fit on a J model. You guys have any idea how to solve this?thanx

Is this a question from fifty years ago when one could walk in a store and test vacuum tubes to fix your own TV or radio?

On my latest build i used 1000 katana 32mm ovalbores and J rubbers both of which have no vac ports so made these adaptor plates which incorporate them.
The plates were initially needed because the bore spacing on the carbs is different to the head .
