I have a np203 t-case on my truck that is on 35s and has 3.73 gears. At 45mph on the dash, I'm going 55mph actual. After pulling apart the gears I see I have a 19 tooth steel driven gear and a 7 tooth red plastic drive gear. Found with some calculating I need either a 15 tooth steel driven gear to match the plastic gear, or a 9 tooth plastic drive gear to match the steel driven gear- both of which do not exist. Any ideas on what to do in my situation? Thanks!
