Has anyone found a clutch slave cylinder that does not leak? I'm on my second OE style sold by all of the Pantera vendors, and it is leaking after approximately 5 months/750 miles of driving. This is getting really old, having to replace them every few months (had the same problem with the master - using a Wilwood now - no problems). Is there a non-Pantera vendor part that anyone has adapted to fit the Pantera??
