Did 1973 318 V8 come from factory with plastic teeth on timing gears?

Thanks for your replies and pictures. Mine is a 73 Swinger also with 99K. I am not sure yet if that is a problem but a lot of other plastic mechanical parts on the car already broke.

Be a good idea to change it.
You're more than likely pick up lost "umph" when you hit the pedal .
