FS: 2001 15/16" Brake Master Cylinder/Brake Booster
FS: 2002 15/16" Brake Master Cylinder/Brake Booster AND PROP VALVE
EDIT: I found the original information from the previous owner. This is from a 2002 SPORT SE model, could not verify ABS or not from previous owner. The third outlet on the MASTER CYLINDER suggests NON-ABS, but other photos have shown that NON-ABS brake boosters are considerably thicker. I could not edit the thread title.
Bought this a while back for the 7/8" to 15/16" upgrade (improved feel). The lines into the BMC need to be bent and OG Miata owners say the NA lines have enough slack for those modifications. You NEED the booster to go with it as NA boosters won't work with NB boosters (will have more links available).
Finally did 1.6L>1.8L rotors/pads upgrade but decided not to go with the BMC/BB/PROP VALVE upgrade as well (to finish the job asap). Rather not hold onto it at this point (relocating, minimizing baggage).

Got lazy to do the extra work. =(
Typical reman BMC prices: $70-100
Typical NB booster prices: >$150
Prop Valve: $50+/-

Oh, and FYI, here's a bit from Keith @ FM:
You have a 01-05 Sport & MSM non-ABS booster, which is the preferred booster, as it lets you mount a MC brace on a STB. The sport+ABS/non-sport booster is too thick.

1990-00: 4.74:1 <- this is a bit approximate, as Mazda gives a range of output pressures as acceptable
2001-05 non-Sport and Sport with ABS, except for MSM: 9.7:1. Yes, that's about double. This booster is visibly fatter, and I suspect it has dual diaphragms inside instead of a single.
2001-05 Sport without ABS and MSM: 6.4:1
