There mounting bolts inside and outside the cowl on each side. The inside bolts are no problem, but the outside bolts are flush against the inside of the hood. I think even if I could get a long open end wrench on them, there'd be no place for them to go.
I was thinking about two people getting on each side of the hood, near the cowl, and lifting up the trailing edge of the hood. The problem is that it clamshells open before lifting up. It's supposed to be the other way around, lifting up first so that the hood and cowl don't start off scraping metal to metal.
Thanks for the suggestions. I'm still thinking on it.
