Yeah, I'm pretty sure someone put the wrong head bolt there. You should have had at least one more threaded head right between the 1 and 3 plugs. I think they probably moved it to the front for the ground in the later years so they could use the second one for the front end of the exhaust shroud. It's missing on yours and that's why they put ground on the ps bracket.
