I came to the realization that there should be a panel in both front wheel wells that covers the rear of the headlights. Looking at the attached photograph, there are at least three mounting holes circled in red. Does anyone have a photograph of this part? I tried to visualize it using the Futofab site but there wasn't a clear image of it.

Somewhere in the 260/280 range, they added entire front wheel well liners in plastic. I imagine they install where you indicated. There are two versions.  Not aware there were any such thing on 240’s (all North American references)

Fiche details about liner parts

This was a April 1974 260z so I would of thought that it would of also been on some of the 240z's. If its part No. 63830-N3600 and 63831-N3600, then it looks like you are correct that its a 260/280z part. Maybe that will make it easier to locate.

I think the part I'm looking for is 64186-N3600 and 64187-N3600 that is identified as part 80 on the diagram. 

 

BTW: I finished my caliper rebuild so after nearly 2 months of waiting on some parts, I can drive this thing for a few weeks before it goes into hibernation. 

I think this listing has one of the two: https://www.ebay.com/itm/176235020346

It looks like the seller is only about an hour away from you, too.

The asking price for this part seems very lofty. If I can find one that I can scan or use to make a mold, I think I can churn out a few possibly using a vacuum form method. I've never did a vacuum form (excluding back when I used a toy in the 60's), but I have a unit available nearby.

Would anyone be willing to do a 3D scan of the convex side of one of these? I think I can create a left and right mold from this to try to vacuum form these. Scanning can be easily done using a cell phone with the free version of the KIRI Engine app installed (https://www.kiriengine.app/ ).
