Here is a used set of 10 spline quick change gears. They are set # 9. 19/23 tooth. They are 4.99 ratio with a 4.11 ring and pinion and 5.88 ratio with a 4.86 ring and pinion. I used these in a vintage dirt race car and they worked good, no issues. Some minor pitting on a few of the teeth. Any questions please ask.
