Fellas- The fun never ends; Today I went to get an expansion plug to use in the hole in the head (rear) across from the water temp sending unit. The brain trust at my local NAPA informed me that no, I need 4 plugs in the heads, not just one. They also told me the size of these plugs was 1.788, which I recognize as the size plugs for the block. I stood there repeating myself until the counter person told me I didn't know what I was talking about, at which point I left empty-handed. I had nearly the same experience across town at the Carquest store.Would someone happen to know the correct size of the plug, so I can try it that way tomorrow? Maybe I'll have better luck doing it that way... Thanks, /Duck

BOO- YA!!!
