June, San Jose unrestored under hood courtesy group lamp & related wiring pictures.
Notice the late-design rolled lip openings in the hood and the Turn Signal later design harness (like used also in 68's).
The metal retainer at the lamp and the locator at the bottom of the hood, are not found in any aftermarket sources. The locator is molded around the wire originally. Getting one off a donor car can be a bit difficult too but if you do not destroy the locator, you can drill out the old, damaged wire slightly oversized and secure it to the Alloy Metal reproduction wire.
I believe I initially was looking for a factory lamp and eventually, I did come up with one. Using an original and the reproduction wire and fuse holder, I made a decent one up.
Again, you need hardware that isn't easy to find nor is it reproduced.
