Does anyone use a dash mounted vacum gage to monitor their manifold vacum? If so, where is the best place hook up to? Manifold, carb, or disc brake vacum line?

any full time vacuum source is fine.
doesn't matter where it comes from liong as it's not ported (spark) vacuum.
yoiuc an watch ported vacuum to see how your vacuum advance will behave, however.
