For everyone's information, I just looked on rock auto under 70 dart and they do have several left hand thread wheel studs listed, looks like a bunch are on close out. Might be worth looking into for people interested.
There is something wrong with some of their information. 70 Dart never used 11" brakes and all the studs I have had were 7/16" threads instead of the 1/2" they are listing on some of them.
