Well I know it's been a bit but I figured I'd post this anyway. I noticed one of the guys I work with today doing a tune-up on a 4.3 Blazer. I figured I'd ask him how he prefers to tackle that nasty spark plug. He said he uses the same Craftsman spark plug socket I use 'cause it's shorter than his Snap-On spark plug socket, a wobble extension, and a 19mm crowfoot socket like the one I photographed. I haven't tried this method yet but I will next time I get one of those.
