Manifold vacuum outlet

Hi,
My first post!
Looking for advice, I don’t appear to have an outlet for the vacuum hose to work my wiper motors.
There is one for the rocker cover and one for the brakes.
I wondered if I should drill and tap the main manifold outlet and fit a length of pipe?
I tried attaching a photo but can’t get it small enough to attach.
Any advice appreciated!
Regards

My driver side wiper motor is the only that works fine.I already changed the right hand exhaust valve wiper and it continues not working.

This is how my 353 Open cab (6-45 build) is attached to the manifold. It uses one side of the hydrovac hook up. The side that is not regulated pulling full vacuum off the manifold.

The line coming off the top goes to the wiper motors.
