doing an upgrade to duel circuit, is the only compatible unit , a kombi one or can you use a beetle or type three duel circuit m c?is it true that you don't have to use the booster to fit it to the split or will that labour the master?

I belive you use a dual circuit Drum/ Drum MC from a 68 bus then you get an adapter (big bush sort of thing) and an extended push rod.
I have a new in the boxmaster cylinder if you want one (dual drum) Price one up and make an offer if you want it.
