Here is a used set of WINTERS 10 spline quick change gears. They are set # 23. Gears have 22/33 tooth count. They are 6.18 ratio with a 4.12 ring and pinion and 7.29 ratio with a 4.86 ring and pinion. I used these in a vintage dirt race car and they worked good, no issues. No chips or major damage on the teeth, good used condition. Any questions please ask
