Looks like the ones Floyd offered you will work.
I was under the impression that 1970 models all got RH thread studs. My '70 'cuda and a '70 road runner I used to own both had RH studs on the driver's side when I got them. So unless they are late build cars, they had been changed prior to me owning them?
