Hi Rob....as per one of your earlier posts/reply's to my questions you had mentioned that a 13/16 deep socket was required to un-screw the spark plugs...I purchased a 13/16 deep socket at Princess Auto....the socket was the deepest at 3.0 inches overall length....it does not fit....it appears that a socket to fit the depth of the plugs would required an additional 1/4 inches of length. Any idea where to buy a longer(3.25 inch long) 13/16 deep socket?.....I really do not want to spend $40.00/US to order a special plug socket wrench if I do not have to.

Thanks for all the other great ideas and tips.
