To Clarify; the Power Lock (Powr Lok) is a clutch type. The OP’s 489 could very well have been a cone type, which is vastly inferior to the clutch type.

Most would agree the clutch type IS the way to go, and Doc is the man. There are Eaton Tru Track fans, and some detractors.

I run a clutch type, wouldn’t have it any other way.
