Having problems getting the (#7) spark plug out of the 69 GTO, the one closest to the firewall on the drivers side. Is there a trick to removing? Standard 350 hp 400 ci motor with auto transmission. Both the battery cable metal tube and steering wheel column bar that connects to the rag joint is in the way. I've tried both short and long extensions as well as the 90 degree adapter on the ratchet, but cannot get the socket over the plug to remove it. I don't remember having problems with driver side plugs before, it's always been the passenger side that I've had to Jack the car up and remove the wheel to get to plugs due to the A/C unit.

From a mechanic viewpoint that has worked in many GM dealerships, either a flex handle 3/8" ratchet, or a spark plug socket with a universal made right on to it and a long extension. Either of these were my go to tools for removing spark plugs in any car when doing tuneups etc. requiring spark plug removal.

I use a deep spark plug socket that has the hex built into the end of it. Put it on then use a combination wrench to break it loose.

That's the best way.

One of each of these will make changing all your plugs easier and faster, not just #7 in your A body. With an extension your ratchet will be out in the open free for you use the whole range of the ratchet handle. A swivel head ratchet is much handier than a straight handled one in many situations where space is tight.

OPs choice. From the looks of the fleet you have listed, your going to be changing plugs more than once every couple of years. I have one 13/16" and one 5/8" sockets.

X10!!!! For the last twenty five years I used a flex/universal adapter on my ratchet on that plug. I finally bought a deep well socket with hex on the end and turn it with an open end wrench. Not easy being a cheapskate sometimes! BTW, with manual brakes and no AC I can change the other seven with a four inch extension/ratchet VERY easily! Good luck!

Up-Date-

I did have a spark plug socket which had the hex on the end. Put it over the plug and still could not get the adjustable wrench on the hex. I had to loosen up the battery cable tube, and the plug wire holder from the block, just to barely get the wrench on the hex. Was able to break it free and use two fingers to unscrew the plug out. Looks like it had been there for a long time. Was able to get the new plug in and tighten back up. Note to self, go buy the correct tools for the job! Thanks for all the help!!!

Just an FWIW, using a standard spark plug socket coupled to a separate universal joint is not the optimum setup. It makes the overall length too long causing interference.

You need the spark plug socket with the universal made/engineered into the socket.

I use a 36 inch extension so the ratchet is over the fender where it can be turned easily.
Anyone that has worked as a flat rate mechanic has two of these sockets in their toolbox. One for 13/16 and one for 5/8. You'll save time, and not spend as much time leaning over the fender in a RWD chassis, especially if you have back problems.
