The hydraulic clutch system utilizes Girling slave and master cylinders.  The slave is mounted to a 1/8" thick stainless steel plate that shares the bell housing/engine block bolts.  An aluminum heat shield was added between the header and slave before any overheating problems were encountered.  The original clutch actuation arm was cut off, and a new stainless steel arm was welded in its place.  The original arm extended down from the shaft, while it needs to extend upward for this application.
