Your Chevrolet clutch will be lined with leather unless someone has changed it.

I have a 15 Maxwell that was lined with woven brake lining like material from the factory - it works well. I have not encountered a cork lined cone clutch.

Some people have relined cone clutches with Kevlar with varying degrees of success. It tends to continually grab in some cases.

I use my 1911 Buick often & it has a leather cone clutch. As Brasscarguy states, Neatsfoot Oil is the proper treatment if the clutch is grabbing; Never use motor oil!

Fuller's Earth, which is like very finely ground cat litter, will help if it is slipping.

I find it helpful to hold the clutch open & wash it out with brake kleen once in a while then reapply the Neatsfoot Oil.
