    What clutch fluid have you been using?

    Some years ago the re-done clutch in my '37 was chattering slightly.  I started using Dr. Doug's version of Hudsonite, and the chattering went away.

    did you have the pressure plate and flywheel surfaced?  If the surface isnt smooth it may not be the clutch.

    The clutch no longer a problem as we drained out the ATF and installed one 6 oz  container of Clutch fluid that i found hiding in the trunk. The HET Club used to sell it and i never tried it until today,  The cork clutch is now Smooth as it should be. I just never trusted it before, now I am a believer of it.    Thanks so much to all.  Hudsonly Rudy B.
