[Chris in WNC]

Synchro99- I bought a Model A in 1990 from a middle-aged lady whose husband had no interest in cars. So she had it serviced by the Exxon dealer down the street. It only had brake rods on three wheels......

Taking the advice of the late Roger Kauffman, who was MARC technical advisor for years, I always run straight STP in transmission, differential and steering box. No problems.
