|I bought the brake booster and brake master cylinder as a unit attached to each other from one car. The ebay ad is referenced above.
Justin and I were looking into the possible differences between models yesterday as well and couldn't tell if there actually was one? It looks like all of the boosters are the same...but I can't tell if the BMC is different on the models that came with Akebono brakes. I would be curious to know this and if it makes any difference.
