Don't blow a head gasket, I know that it's not a real important issue but it's still something that is part of what will have to be addressed eventually. I kinda think that you don't like it because you know that I'm right on this one. I've changed out many a third member in my time and or tire sizes and found that my speedometer didn't read correctly. If you don't want to believe me that's fine, simply call your local transmission or tire shop and they will tell you what I did
