rear plugs are easy. remove them two dog bones from the engine, with a ratchet strap pull the engine forward, this will let you see and have about 3 or 4 inches more to work with.
the one rear plug is sorta blocked by the o2 sensor. i put the socket on the plug first, then use a 3 inch and a ratchet and just stick the tip of the extension in the socket, and break it free.
if your using a real spark plug socket, (recommended, its got a foam insert) it has a bolt head on it, you can use a wrench on the socket as well if you like.
