[DeTomaso] clutch MC bore and stroke?

JB, what are you trying for here? Not trying to discourage you but there's 
so much mechanical play in the clutch linkage from the pedal to the disc on 
most Panteras, that it's hard to say what the measurement might actually be. 
All the pivots in the under-dash effort reduction linkage (if present) are 
steel-on-steel and have never been lubricated since the car left Italy and 
maybe not even then. The clutch release on the bellhousing cross-shaft uses 
bushings (early) or needle bearings (late) and those have likely never been 
lubed. Note the early cars used a different (smaller) MC bore than late ones; 
not sure on early/late slave cylinder bores or lengths.
A rough gauge for wear is to step on the pedal and see how much travel you 
get before the bellcrank lever starts to move at the bellhousing. I've seen 
1" of pedal-travel-slop in some cars (excluding minor hydraulic leaks); our 
'72 L had over 1/2" before I went to a hydraulic throwout, and I suspect 
most Panteras will have their own unique number. Note this is not 'free play' 
between the bellhousing clutch fork and disc; that will be in addition. Good 
luck- J Deryke
