      There may be a few variations but for the most part:
      FS01 = Probe/MX6/626 HLA cam
      FSD7 = Standard Protege/626 SLA cam
      FSH9 = FSZE SLA intake cam(also found in some euro and aus. FSDE's)
      FS9P = Rare Mazdaspeed SLA exhaust cam
      FP39 = 1.8 FPDE SLA intake cam
      FP47 = 1.8 FSDE SLA exhaust cam(very similar to FSD7 exhaust cam)
      FS1G = 2000+ Protege/626 revised FSD7 SLA intake cam(emissions)
      FS1E = Torque biased cam from 99-00 Japan and Euro MPV.
