[DeTomaso] clutch MC bore and stroke?

[John Buckman]

My original '71 clutch master cyl bore is 0.685" (17.4 mm).
Stroke is 1.25" with the short push rod that is used with the clutch pedal effort reduction kit,
and 2.375" with the long push rod that is used without the clutch pedal effort reduction kit.

OEM slave cyl bore is 1".  Max stroke is 1.625".
Long throw slave cyl bore is 0.75".  Max stroke is 1.125".

What is needed (and I don't have) is the actual travel of the slave cyl piston from at rest to full
disengagement of the clutch disc.  That would give us the amount of fluid that needs to be displaced.
My guess is that that travel (stroke) is around 0.875".
