I've seen some posts on vehicles that had factory elec. vac pumps for the vac booster. $269 for one from Summit seems high, and I kinda like poking around junkyards. I've heard diesel Olds and Caddy, but parts stores dont know what I'm talking about so I dont know what to look for. does anyone know?
Hit the junk yard early eighties x and j bodies (firenza citation etc ) have them. I used one in my chevelle with a lumpy roller cam .The power brakes worked great.
