There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.
not fun, but with practice you can do it. Because socket wrenches are too fat you have to use a spark plug socket that has a hex wrench end on it (most already do), use a box end or combo wrench to turn it. Those can slip into that tight spot.
