I have a 92 fuel injector to be replace, but I broke the cover that goes on top of the injector.... Sooo my question is this: will a 93+ injector cover work for the 92- injector? They are different looking, I believe the rubber piece is a little bigger on the 93+ covers. Can I shave the rubber piece down with a razor blade to fit the cover? I have broken 1 92' cover and 2 93+ covers tryin to fit them on.
