All the master cylinders interchange, and so do the boosters,
AFAIK.

1977 MY used a one-year-only part, 911.355.027.00, for both 930 & 911S of that year. A guy with an otherwise original '77 930 was very happy to take my booster when I upgraded to a late 930 servo, M/C etc for big brakes, as his had failed.
1978 up, SCs, 3.2 and 930s used a different booster, 930.355.027.00. The 85- turbos switched to 930.355.027.02.
I think the 78 on boosters are 8" diameter rather than 7"; bolted straight in to my original pedestal. Pretty sure the 85-up 930 servo has a bigger "slave" or "assist" ratio, hence my choosing it (but my pedal still feels like there's a block of wood under it).
Also pretty sure I got that from information Bill V posted. He's the man to ask.
