Here’s the MC I ended up getting for my ‘63 Catalina.
Fittings on both sides and can be used with or without a booster and can be used for drum-drum or drum- disc setup. I got the aluminum version for less weight and no rusting. Going to change to a cad plated cover.
No, it has not been plumbed yet. Plan to use the outside ports and an adjustable distribution block. Scarebird disc on the front and drum rear. Manual brakes.
