LH and RH Thread Lug Nuts

[440 Charger]

Having 1962-1963-1964 Plymouths and Dodges---right side=right threaded studs---left side (drivers side)=left threaded studs. Just weighting in.

Thank you.

left hand nuts go back to at least the 1800s with the Conestoga wagons and Studebaker wagons, which were the primary wagon for the Union Army during the civil war. Most likely the nuts went left in Roman days. During World war one General Pershing insisted only dodge trucks be used in the war, as they could run flat out and the wheels would stay on, as compared to Fords. and when WW2 started the Govt mandated all Military vehicles have left hand thread on the driver side. But, after the war GM and Ford went back to their old ways. (not sure what year)
I get a kick out of watching Gunsmoke, , where Quint the Blacksmith is working on a Wagon,(studebaker is stenciled into the frame) and the writers were accurate in portraying the original wagon where quint is tightening the nut left with a really cool unique tool to fit inside the hub.

apparently Mopar people were strong on safety and reliability, VS the competition, and very stubborn as well!Lol

I know this is an old thread but I left a question unanswered. That owners manual came with the car when it was delivered in California in 1964.

Since this thread was resurrected.....
The left hand thread on the left of the vehicle goes back a couple hundred years for wagons/coaches that only had one nut holding the wheel on. Single nuts/right hand thread would loosen on the left side.
Same reason knockoff wheels on british sports cars (and 63-66 corvette knockoffs) have lh threads.
Apparently, many engineers thought it was still a good idea, even with multiple bolts holding wheels on. Since been proven unnecessary by billions, (maybe trillions) of miles driven with rh nuts on the left side.

When my dad had Chevy pickups for work (drove Mopar cars otherwise), I felt a left front wheel knocking. Somewhere someone didn't get the lug nuts tight enough and they backed off and backed off several threads. Was in a 20 mph zone and pulled over and popped the poverty cap and found it. Can only imagine being on the freeway that day?? Made me a believer in left handed lugs....but....if they were tightened securely, they probably would not have backed off. This was back in the late 60's.

Heck still trying to figure out why most Mopars have 5 leaf springs and I have 7?

If original you would have 7 on one side, 6 on the other.

If original you would have 7 on one side, 6 on the other.

Or is it 6 on each side?

5 + 2 half leafs = 6
