My clutch setup uses the Wilwood PN 260-1304 master cylinder with a Perfection PN 37837 slave cylinder. This arrangement works ok. You could also get the parts from Backdraft's parts department. Shielding the master cylinders (brakes and clutch) is worthwhile but even so a clutch fluid change every couple of years remains a good preventative move. I'm coming up on 40k miles on #168 and have never had an out-and-out failure, but did change out both the master and slave a year or so ago as I was getting some inconsistent clutch response. It cured the problem.

Good luck!
