   I know this has been discussed before but when you learn something the
   hard way you feel like you should share your misery.  Soooo.  I bought
   a new clutch master cylinder for the 69 I recently purchased and
   am reserrecting after it sat for 17 years.  After getting the new MC I
   decided to put it on my 1970 and put a rebuilt one from my 70 on the
   69.  The .75 MC and clutch combo works much better as the old MC that
   wasn't getting all of the hydraulic pressure to the slave.  However, I
   discovered that the 1969 clutch MC with the .75 inch diameter piston
   is much harder to depress than the .70 inch piston I previously had in
   the 1970 (VIN number after about CC53,000).  I may just yank the new
   .75 MC on my 1970 and rebuild an old .70 inch MC that I have lying
   around.

   Considering the improvement (my personal preference) of the .70 over
   the harder to depress .75 inch clutch MC is there any other reason
   why we shouldn't recommend the .70 inch clutch MC to our listers?
