brake master cylinder leaking

My series 3 hybred has a leaking brake master cylinder (dual system ) were it joins the servo,problem is cylinder is marked Ford no other numbers. can anyone tell me if a 80mm hole pitch were cylinder meets servo is landrover sizeing or have i got a ford servo, as want to renew with part 90577520/ nrc 6096 cylinder if poss to servo

As you have an Series III hybrid which is using Ford parts, I would be inclined to replace like with like!

Many thanks for advise, but the trouble i have is no motor factor can identify the ford cylinder ,and dont want to reseal as bore worn ,i suspect servo is landrover hence wanting to find out if 80mm hole pitch is landrover spacing so can fit correct part
