I have never heard of a steel cam gear...the crank gear is always steel. The aluminum gears were used on trucks, and sometimes were sold by hot rod shops under the guise of 'heavy duty'. The fiber gears were suppose to be a little quieter...they lasted forever.
I can see no reason to change from fiber to aluminum..yours has lasted 40 years, to me that proves the durability.
