Bowtiekiller you have jinxed yourself....you should never tell anyone or speak outloud that you have gotten away with something for so long. .........The Mustang demons are now dancing around your car waiting for you.... Seriously though, a little insurance by adding the pins does not hurt. I went two years before I put mine on. Mine never popped up or anything, but I put them on for insurance. I dont have the extra cash to repair all the things that I need to, so I need to make sure that something doesn't happen cause I didnt take an extra step to prevent it.
