Charles,

The front and rear are the same part # for the LH and same part # for the RH thread, see attach.

I’ve seen the RH on several auto part sites from Raybestos and Dorman although LH ones are not listed.  ???  :o

NAPA should be able to get the left hand threaded ones for you (if they don't stock them at the store), right hand thread should be easy.

Charles,
Why not make them all "Right Hand" studs, and avoid any more issues.  Less hassle.....I always wondered what they were thinking mixing right and left hand threads together.

Bobby,

One reason I’ve always hear was for the lug nuts to stay torque and not to come undone when driving with the wrong thread lug nut/stud on that side wheel. But…!  ???

What if someone (shady mechanic) reverses the drums?  :o

So sometimes the easy way may not be the safe or correct way. But..!  :-\

I would venture to say that most all cars built since 1960 or thereabouts have used right hand thread wheel lug bolts on both sides.  The idea that they might come loose proved to be false if properly torqued --- which you could say about left and right hand.  Converting to right hand threads on the left hand thread side is the reasonable thing to do --- then you could switch drum sides (by mistake?) without issue, at least as far as the lugs are concerned.

I've only seen a wheel come off once in my life. And that was because the "Kid" went to lunch and forgot to tighten the lug nuts  ::).   It was a Porsche 911 and the owner's Wife was the one picking it up. Needless to say, it was not a good situation. Luckily, no one got hurt......

Charles,
  Not to be too particular but all lug nuts are not created the same. The beveled angle that seats against the wheel has more then one angle. I've damaged some wheels by not adhering to these angles. Not rocket science but if your buying lug nuts why not get the correct ones for your dollar?......walt....tulsa,ok

Charles,

Couple of comments:

Doorman makes these. NAPA should have a listing or go on line.

If you are interested on the right vs left hand thread check it out on Google. Interesting story and film about Chrysler and their reason for doing this (in the 40's if I remember correctly).
