Here is a used set of WINTERS 10 spline quick change gears. They are set 34. 21/29 tooth. They are 5.69 ratio with a 4.11 ratio ring and pinion and 6.71 ratio with a 4.86 ring and pinion.  I used these in a vintage dirt race car and they worked good, no issues. Teeth are in good used shape, no chips or pitting.

Any questions please a
