I have a '53 3600 with 4 speed transmission. The rear end is marked on top "L0224" to the best that I can determine. Where can I find the info on that particular rear end? I would like to know what my ratio is now. I would like to change out the "guts" if that is possible and put in gears that will give me more speed as I have the updated brakes and will not be using the truck for heavy hauling.
