    Default '58 Heater/Blower to vent connection

    I recently purchased a replacement blower motor and cage for my '58 and am working to put that back in the car. When I got the car, it was not installed so I was not the one that removed it and think I may be missing parts.

    Basically I'm trying to figure out what goes between the blower motor housing and the vent/input that is under the passenger fender. The blower motor housing seems significantly smaller than the vent piece (right before the vacuum activated flapper valve). Was there a rubber donut or something that adapts the two?

    And my vacuum actuator is leaking. Any suggestions on where to get another one?

    1957s with a similar setup had a rubber sleeve to connect the two which is available at This diagram may help ID the part, good luck,
