Here is a used set of WINTERS 10 spline quick change gears. They are set # 15. 19/20 tooth. They are 4.34 ratio with a 4.11 ring and pinion and 5.11 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 damage on a few teeth. I used these and they worked well. Any questions please ask
