    The later style has a brake light switch that mounts to the pedal cluster.

    dual circuit cylinder in early car

    I used a BMW reservoir modified to mount in the original location because it has the partition inside to separate the fluid between front and rear circuits. I also used the original pressure switch by installing another banjo at the master cylinder. Later picture shows the plastic spacer used on the reservoir bracket screw.

    The mechanical brake light switch doesn't mount on the 67 and earlier pedal clusters.
