HELP1. Changing spark plugs on my 300G, Autolite 86's. Question: Just pulled last one towards firewall on passenger side, there's an extension, about 1" long with about 1/8" hole in the end. Also when looking in the cylinder there's another 1/8" hole. What the heck?2. What is the vacuum canister for on the drivers side wheel well?3. Just ordered brake parts from NAPA per club list. The master cylinder assembly, part # 30000, NAPA say's it's for 58/59 300, 61 Newport with manual brakes. Is this correct? I didn't order it until I find out for sure.Thanks much!Mike 300G--Marshall Larson
