Lets see what the clutch fibers look like. Hold the reaction support up to the light. Are the ring grooves square? Or are they worn tapered. Are the rings worn on the sides? How about where the reaction shaft support rings ride in the drum, worn? 4 clutch drum should function fine with a Turbo Action rmvb. Have you checked the pressure regvalve and spring? I'd be testing the resource when its backtogetherT/A arent real high 120ish.

Rings look good,grooves as well.
I ordered a kit with Teflon seals and a roller rear support.
