I removed the top louver and the armor at the top of the louver assembly and that allowed a little more access to the three nuts for the center hood panel. A 9/16” wobble socket is still too big to fit in the gap but I think Outsider’s suggestion to modify a wrench might get it done (thanks Steve). There’s about a ¼” gap between the bottom of the center hood panel and the angle that lives under it and going by the rivets going across each side of that angle, and none across the middle, it looks like the hood wings close on a ¼” welt and that the non-moving center panel is supposed to have about a ¼” shim under it. There is no illustration to show it but it makes sense that something would need to keep all three hood sections on the same plane. Looks easy enough to make if that’s the case. Is that the “Filler, hood plate, center, top, frond end” part called for in the parts manual?
I tried to attach pictures but couldn’t get them to go.
