I need to purchase the correct speedo gear for my 1970 T/A with an M-20, 3;55 rear gears and 25.5 inch tall tires (15" rally 2s). Looking at George Pearsons Speedo gear chart I need either: Blue with 20 teeth "WB code, or Green with 22 teeth "WL" code. I do not know what the "WB" or "WL" codes refer to. Anyone here know what speedo gear I need for an accurate speedometer reading? Thanks.
