I have two flyweels one has 130t, the other has 131t. I also have the starters that came from the same two cars, they both have 9t gears on them. Does this seem correct? I have heard that there are 8t gears and 9t gears for starters. The reason I am asking is because I need to put a ring gear on to my new aluminum flywheel and the one with 131t is kind of chewed up a bit. That is the one that I just removed from the car. The 130t ring gear is in better shape. So does it matter which ring gear I use?
