70 dart units have screw in studs into fiberglass. the 71-72 are pot metal and rusty nuts and corrosion tend to snap them.
I have real 70 with studs in many colors
News to me, learn something everyday I guess as the ones I have are exactly as you describe, crap. Are you saying you have a pair of fiberglass ones with functional studs you would be willing to part with? If yes please let me know, PM if you like.
