Whoa pardner. From the beginning, Mopar put left hand thread studs on the driver's side of the car through the 1972 model year. Many have been broken off over the years by apes with air powered impact wrenches. Some were replaced with LH studs others with RH. The stud should be stamped RH or LH depending on the threading at the end of the stud (visible with the wheel on the car. Make sure you know what you're starting with before you get going too far.
Suggest checking the rear axle on the driver's side to see if it has LH studs. If so, then the front should be LH also, just to maintain some sort of consistency. There is nothing "wrong" with LH studs. The idea was that the forward rotation of the wheel would encourage the nut to tighten if it was to move at all. Dorman makes LH studs in a variety of profiles. I used them on two 66s I restored.
