I found a comment which makes sense to me.

Flywheel ring gear was changed from 160 to 157 teeth to improve starter =
gear
engagement.
=20
Ring gear OD =3D 13.258"    circumference =3D 41.65"
41.65"/ 160 =3D .26"
41.65" / 157 =3D .2653"
=20
Maybe this is why my 160 tooth original ring gear was all chewed up.
=20
I have not found a date when Ford made this change to 157 teeth.
