Brakes - What servo & Master cylinder?

[Fastpedeller]

I think the following is a combination which will work for Front discs and rear drums, whilst also being fairly compact and having dual circuits and low-level alert switch - can anyone confirm if the parts will fit together?

Series 2a and 3 servo (6" diaphragm) part STC 1816
Defender master cylinder (non abs) NRC9529

Thanks in anticipation.
