Well I thought I took pics of every part and from different angles but I have hit a snag.Looking at the pic the Left Lever 37T gear,Rt Lever 45T gear.Question--Pt#10-1553 20T gear is for the Lt lever and Pt#10-1512 20T gear is for the Rt lever,one 20T gear is larger than the other 20T gear which gear goes w/ the left lever??? I can't tell by looking at the diagram,but it looks like the larger goes w/the left lever.Just started and I'm lost,thanks for some direction---Kroll
