OldSub,
Yeah... I am old timey... but I have an auxiliary electric vacuum motor on the firewall. Should put out enough vacuum to really suck.. just like our wet weather.

But what about how the transmission arm mounts to the motor... that is what I really want to know. The manual I have doesn't have much about the motor in it. I have a build book coming though.
