Does anyone know what size the treads are for the port directly behind the carberator. I need to get a fitting for my transmission vacuum line.

As always, thanks in advance.

Why not use the port on the drivers side of the carb? That is actually where Edelbrock recommends for tranny vacuum.

I have a Holley dp and my vacuum advance hooks into the side of the carb and my pcv hose hooks into the back of the carb. Only place I have left for the transmission vacuum is the port behind the carb.
