Left Hand Thread Wheel Studs

Does anyone have any NOS or good used Left Hand Thread wheel studs for a 1970 Dart? I am after both the studs for the front disc brake Mopar P/N 2768029 and for the rear drum Mopar P/N 2070159
I got rid of all my left hand thread studs and installed all right hand studs. Any reason why you wouldn't do that, other than originality? I can't remember what I did with the left ones, I'll look tomorrow and see if I can find them.
