need help Bad-excuse me for being stupid

well, I am not sure that they are what goes in there. I cannot take a pic of the hole. I have enough room to get my hand between the manifold and the shock tower. as far as the chebby plug comment goes, I looked the plug up on Summit's website and the only application for that plug was for a chebby. according to the parts house, it calls for RJ14YC. I am going to look into this next week. we just finished putting a new tranny in juniors Dart Sport tonight and my wife has major surgery Monday morning so right now this is the last thing on the list to do. I appreciate all the help. Bill
