Incomplete clutch disengagement problem

[oldchevyguy]

Anyone else have G96-01? What master cylinder are you using?

I recently purchased a GTM with a very stiff clutch with Mendeola trans-axle. Turns out it had a 7/8 slave and a 13/16 master cylinder. After researching all this the master cylinder should be 1/8 inch smaller than your slave cylinder (industry standard). I replaced with a 3/4 inch master and it reduced the pedal effort I'm guessing 30 some percent. Still stiff but the clutch has springs for a 700 ft pound rating and will always be stiff. Sounds like you have the correct master and slave (22.2mm = 7/8) if they are both working correctly. You might try adjusting the pedal height for more travel with the master cylinder also.
