when I turn my head lights on my blinkers will not work.i have replaced the head light switch,both flashers,all bulbs,rear sockets and checked all the grounds.also is a 1970 rear side marker light sockets supposed to be metal that ground to the housing?
I know you said you checked the grounds but did you check the ones in the front behind the valence and bumper, I had a similar problem and that's what fixed mine.
