For sale is an excellent Winters #8514A quick change gear set with 20 and 28 teeth.  This is set 14A and in a 4.11 ring and pinion rear end this yields a final ratio of 5.77 and in a 4.86 ring and pinion rear this yields a final ratio of 6.80.  This is a 10 spline gear and very nice.  Thanks for looking and as always I combine shipping when possible.
