gear tooth count?
What is the gear tooth count...Sure looks like a 41 and 15 gear count. which is a 2.73 gear set. The 308 is something else code etc. Please count the teeth as this is what will determine the ratio.
The ring in the pictures has 41 B 15 GM A U 308 3
The 41 B 15 is your ratio those are the count of the teeth on the ring and pinion. Count them and see. Jim
