I need some head... I mean a new head... LOL... Mine has casting number 24574683 and I found one with casting number 24574683-18. Does anyone know if there is any difference that will prevent me from using it? I know mine is specific from 1996 to 1998. The guy says it will fit 1996 and up... Any thoughts?
