To see if they're working at all, you can use a timing light. Without
the vacuum advance connected, see if you're getting advance with
increasing RPMs (centrifugal). Then, with a hand vacuum pump + timing
light, you can check to see if the vacuum advance is working.
Determining whether they're within specs would just require knowing the
specs and having degrees marked on the pully or damper that the index
reads against.

Shop manual? Sold mine almost 40 years ago, but as I recall, it was
chock full of allowable tolerances.
