Can anyone tell me what color gear (gears) I would need to have my speedometer to read correctly. Have a 77 vette that I just changed the differential gears to 3.55 and would like to change the speedo gears before I put eveything back under car. I had 3.08 gears/ 225/70-15 tires/27.4"dia.and drive gear on transmission is (Green 7T) and driven gear (Red 21 T). With the change to 3.55 gears what gear or gears do I need to change and to what? Thanks jw
