A friend of mine just got a 92' stang from someone and it has a supercharger on it. When I was looking underneath I noticed there was no flex plate/block plate (have seen it called both of these), the piece between the block and the bell housing, so you can actually see a little of the fly wheel. Anyway the question I have is...would there be any reason that this would have been left off, other than they forgot to put it back on? I don't have any experience with super chargers and didn't want to tell him to get the part if it wasn't necessary or if it had been left off for a reason. Any help would be appreciated. Thanks
