I have the problem with my speedo as most people here, I have bigger gears in the diff, but dont have the speedo gear to let my speedo know that I have bigger gears. I want to buy the right gear for my speedo, but since I bought my car after the gears were installed, I don't know what size the gears are. I'm pretty sure they are 3.73, but I dont want to buy the wrong gear. Is there any way of being able to tell, and if so how?
