I just went and looked at mine, cuz I thought it was a bolt... my fading memory failed me again; my mind's eye was picturing the air pump, which does have two bolts into the head. You _might_ be able to get a stud extractor on the stud, but the extra work to drop the A/C compressor and remove the PS bracket is really not a big deal. Don't lose the spacer!

Rufus is not active on "the wire" any more, but I believe he may still be on pirate. He was very responsive when I was doing my head job last year.

In any event, if you decide not to drop the lower cover, when you get the belt back on, before you button everything up, it should be easy enough to line up the marks and check the cam timing before you start it (it _is_ an interference engine!)
