Hello,
I am trying to find out if this is the Vac advance unit for the 2.0 L '74 distributor, 039 905 205 A .
It has one vacuum chamber, can someone verify this is the correct unit on the correct side?

Thanks,
Mike

Hey Dave,
I see what you are saying, but these are from the Factory Service manual,

Early dizzy

Late dizzy

As you can see the photo shows only a single port for the vac unit, and it is on the advance side, I also read in the Factory Service Manual that "late 74" and up did not have the vacuum advance, just vacuum retard ('75 USA Model Year).
So is the second image a generic photo, or is it the correct config?

Thanks again,
Mike
