a) This is the first time I've read this thread, so forgive the late contribution.
b) My hood is a bit of a mess, but I believe the components to be original to the car.
My car is a '68 fastback, built in SJ on 7 Feb 1968 (actual). The car was repainted but has the original special paint under the red, so I know the hood and the turn signal housings are original. The reflectors and bulb sockets appear to be original, but I cannot say with 100% certainty. The reflectors have holes for clip screws, but I can't tell from my photos if the holes ever has screws in them (the car is a couple hundred miles away so I can't verify at this time). No clips or tape present. The bulb sockets and reflectors are metal. I don't have any photos of the wiring routing, but as you can see the wires were replaced with speaker wire at some point.
I have a donor hood from another '68 that is untouched, with all the original wiring clips, etc. I could add it to the discussion, but I do not not have any info on the car it came from. Should I post pics in this thread?
