About vacuum advances: Last year, I bought from NAPA (with AAA discount),
NAPA Echlin part # VC1165. This is the early type of vacuum advance that is
often recommended here on the list. I have it installed on my '72 Newport
Custom w/440. It works a little more in tune w/the drivetrain than the
original vacuum advance, as mentioned below as the generic on the shelf
part. They found one, in Seattle, which I had the next few days. If you go
to the counter and ask for them to find one, they probably will come up with
one, from somewhere.
*****************
Correct vacuum advances appear on E-bay periodically.
Don't buy a generic from NAPA - I can guarantee you it
is set for 1967-and-later specs.
