Would be a simple change of master cylinder for drum/drum. Likely they probably have one. I specifically said I was converting to disc/drum.

Yes it's a vacuum booster, same as original. The engine should make plenty of vacuum for the original or modern booster. unless the engine is in bad condition or timing is way off. Or you have a performance cam. But you could probably buy their plate and pedal assembly and install a hydroboost on it. No worries of engine vacuum then. But the OE PS pump is half the flow and pressure needed. So you'd have to upgrade the pump or run a second pump. I would love to, but just too much change. But I do prefer hydroboost over vac.
