68' 442 clutch

dan1s · May 14th, 2008, 05:59 PM

Well after 40 years and 40k miles I think it's time to change out my clutch. I have a M21 Munci close ratio 4 speed transmission. What kind of clutch would you recommend.

Also does GM sell the stock springs for 68' 442? If not who would be the best company to match up the stock springs. I want the correct hight.

Thanks, Dan

I've had really good luck with Centerforce clutches. Low pedal force and good holding power.

I would also recommend a diaphram type pressure plate...the one with all the fingers like factory used.

That's the nice thing about the Centerforce clutch. It is a diaphragm but it has weights on the springs so that centrifugal force increases the clamping pressure as the RPM increases. I too have used the high force aftermarket clutches and was not happy. In addition, the extra force caused the tab on the clutch pedal to snap from fatigue (it's only held with two spot welds on the 68-72 cars). I strongly recommend having it fully welded to the pedal arm in any case.
