Why does my original panel have two sets of holes? I don't see any mention of the larger dia hole in any assembly diagram. I should mention that there are holes in the sheet metal of my car, corresponding to both sets of holes.
In the trap door surround (the metal panels) there are many unused round and oval punched holes. Just part of the design made by an engineer or a few of them
Are the larger holes for rubber bumpers or something?
Or were they added my a PO?
The holes you have marked "Hole for?" appear to be inboard of the ones in the metal trap door surround but it might just be the angle.
There are a couple of versions of the over the trap door panel so the hole number and location differ though none are used for any purpose I can find.
Now the question about your inner fiberglass panel holes is a more difficult on since in most picture the area is covered by the trap door. Looked at pictures from over 600 67 fastbacks and could not find allot of examples with pictures of this surface but could not find a corresponding hole in the fiberglass when looking through from the trunk side. When I go to the shop this week I'll see what the panels there show. Must be maybe ten or more of those panels there.
Neither the holes in the fiberglass panel or the body appear to have been added....i.e. they all look factory IMHO.
Its a bit IMHO unusual to find multiple holes made for rivets on original untouched cars (at the outer corners) but have seen a few times more likely the guy got the hole/fit wrong the first time then corrected. Sure makes for an unattractive installation in many cases
Red arrows in this one show the holes in the sheet metal surround
In this one the green arrows indicate the rivet locations - the red arrows the other unused holes in one of the versions of the upper panel
