The vacuum switch just attaches to an otherwise standard part used in millions of cars. The vacuum portion of my replacement switch (the dimmer rheostat in the original was burned in half) literally fell apart. I was able to put it back together better than new. It's a very simple mechanism held together with little metal tabs that may well have come loose causing the vacuum leak.

Hi bp,
I had some success using a small amount of rtv to seal the vacuum portion of the switch on my 71.
I guess it depends on just what part of the vacuum section of the switch has failed as to how successful you'll be.
Worth a try!

Alan

If you've never removed one of these switches the trick is finding the release button for the switch shaft. It's on the top of the switch behind (towards the rear of the car) the vacuum switch. It's a little metal button about 3/16" in diameter and it's directly in line with the switch shaft. Pull the switch out to "PARK" press the button and pull to remove the shaft. Replace by simply pushing the shaft all the way in.

The earlier production switches had issues, but the current batch is running pretty flawless.
