I never had to unbolt anything to do my plugs. Just use a few extentions and buy a foot long pice of rubber fuel line. I forget the fuel line size but make sure it can hold a spark plug tight when you stick the plug wire side of a plug inside of it...the threaded end is outwards from tubing. Then when you go to reinstall the new drivers side plugs, just use the tubing to start the plugs into the head. After that, you just pull the rubber tubing off and tighten them with some extentions etc.
