Another option for cars with low vacuum but want or need to keep the vacuum booster is a vacuum pump. In my not a Pontiac car with very little vacuum I installed a vacuum pump from a Ford 350 diesel truck. It is belt driven works so good I had to install a bleed off valve because it was making 22" vacuum. They are trouble free, last forever and quiet. And less than $100. If that interests anyone I can post specific's and a picture.

I'd be interested in seeing that. How did you figure out the brackets?

FWIW, GM has been using vacuum pumps on most of their diesels as well as some of the smaller displacement gas engines that needed extra vacuum for heater control diaphragms, and vacuum boosters. The 5.7 diesel that came out in 1978 had a vacuum pump in the distributor hole, other applications had belt driven pumps. GM W bodies (GP) had electric vacuum pumps for the brake boosters also. These pumps were made by Saginaw. If you don't want to use a ford part, plenty of GM cars came with vacuum pumps too.
