RE: 80s cars w/vac pumps -- look at any and all small diesels w/power brakes (tink Volvo, Isuzu, VW) and 2.0L powered GMs w/ power brakes. Seems the little OHC 2.0 (late 80s/early 90s) didn't produce enough vacuum for power brakes at low speeds and some have vac pumps. I know my Chevette diesel from years back (84 model) had an Isuzu diesel and the vac pump was mounted on the back of the alternator. Not sure where the 2.0L pumps would be. The bigger GM vehicles w/deisel used a Hydro Boost power brake system that uses the power steering pump for boost.
