Any idea were I can get one of these? All the crossover numbers also say they have been discontinued.
Thanks
Kenny
Rock Auto has them. Do a search on DV1810. Auto Zone also carries them.

GM still had them as of a few years ago...

They still do. The Chevrolet part number is 1973469 (AC Delco P/N D1390A)

Related question: Do any of you have a good 'home remedy' test for a vacuum advance unit (off the car)? I've got a newly built '60 Corvette engine I'm trying to get going and I'm questioning right now if the vacuum advance is working correctly, but not sure how to test it...??
Suck into it and if it's bad, it won't hold the vacuum.
Ed
You could use a mighty Vac Brake bleeder tool to adapt to the advance?
I will try to dig mine out an see.

That's right Jim, use a hand held vacuum pump. Should pull the arm in and hold vacuum.
Or you can save yourself a few bucks and do it the way I said in my reply #5!

Honestly, thats exactly what I would do first, Ed. :)
What Ed said to do really does work! No cost.
basically all the responses suggested 'pulling a vacuum' by 'sucking on it'... Personally I like the idea of using a mechanical device (rather than my mouth) .. :) .. to suck on it! :)
So basically you fellas are saying that if the vacuum can is still sealed, then the degree of vacuum advance should be correct? Or is there some simple means to checking the degree of advance off the engine?
that's correct. It either holds the vacuum or it doesn't. There's no "in-between".
Unless it's an aftermarket adjustable vacuum advance, it'll start pulling at whatever the spec is for that particular can. There's a small tolerance, but nothing worth mentioning.
