Yea Squeeze, that stopleak might work if I never got it on the road. Now that you mentioned that I remember hearing oldtimers tell about stuffing steel wool in the hole and let it catch the stopleak. I don't think this one is even big enough for steel wool.
GMCpanel, Yea I know the different number won't be much problem but I was upset because I've seen very few trucks where the engine and title match. Most people don't bother with it.
