anybody have a source of the weird helix screws that the red taillight lenses are held in with? Or even a pic?
I think they were about an inch long with a machine screw tip and a twist in the body?
These are real original tail light lenses screws I have removed from numerous 64/65 Valiant/Barracudas ... and my taillight !!!
Does this answer your Question ?
Or am I misunderstanding you, my OLD Friend ? ( because these do not even come close to your description! )
