I read quite a few posts regarding changing plugs in a GTO / Tempest and most people had difficulty with AC cars, therefore having to go through the front inner wheel housing on the passenger side.
Even though my car has AC, I was able to change all of the plugs from the topside. I have 3/8" wobble extensions, a 3/8" flex headed ratchet, and loads of adapters to attach them to my 1/2" ratchets.
The one trick I learned years ago was to take one of my spark plug sockets and remove the inner rubber liner. That way you can get it over the spark plug with a much greater angle and when you are up against the suitcase trying to remove a plug, it goes on nicely.
Total plug change time, about 2 1/2 hours and only one small hand scrape.
