I just bought a 1986 LeSabre Hearse. Beutiful car, nice shape. I'm doing lots of preliminary work (Tune Up, fluid changes) and acessing what I've got. A Mechanic has told me to get rid of the hydraulic power brake booster. I have never seen such a system. Does a swap to the more conventional vacuum booster make sense? Will parts from similar full-size GM cars bolt up? I have a good wrecking yard nearby, what parts - if any - can I use?
