Reply to "pilot bushing and throw out bearing"

A tip for those using a modern constant-contact throwout bearing like was mentioned by the Carlsbad guy: adjust your throwout bearing to just touch the clutch fingers after the car is nice 'n hot. Reason is, when the engine and ZF heat up, clutch clearances change. More contact than 'minimal' on such a throwout bearing will unload some clutch pressure, and it doesn't take too much before you have enough pressure gone to cause clutch slippage.

If the above is done properly, you can get a small extra amount of clutch throw with all-stock parts, helping the ZF synchronizers live a little longer during shifting. But you cannot adjust the clutch per the owners manual with a little free play and still use a constant-contact throwout bearing. The two are mutually exclusive.
FWIW, Marino Perna of Pantera East in FL, the inventor of the long-throw clutch slave, has another order into the place that casts these cylinders, so he should have them back in stock soon. His assemblies are made in stainless steel, by the way. I'd always thought the cylinders were adapted from another manufacturer, but I was wrong; they are purpose-built for the Pantera by Marino.
