Had a flat on the ds of my 62 and could only turn the lug nuts a small bit before they wouldn't go anymore.
So I tightened them a bit and tried again.

I noticed when I tightened them they turned easily. When I loosened them they got tighter.

so I tightened them all the way, got tire fixed and loosened the lug nuts back on and she's good to go. 😁

 

Olds finally ditched driver side LH threads in 1964. Chrysler stuck with that nonsense thru 1975.

Be glad you had a simple lug wrench. Tire shops have replaced countless lug studs and hubs because they went after LH thread nuts with an impact cranked wide open. They've also been known to replace a broken stud with a RH thread stud on the same wheel position. Imagine the havoc that created down the road.

Look for the "L" stamped into the end of the stud.

 

I did notice the "L" after I got them off.

It threw me off because I've had the right rear off and it was standard thread.

 

Driver's side lugs (AND the spindle nut) are LH thread. Passenger side are RH thread.
And speaking of Chryslers, a friend of mine owned a 1970 AMX with 390. AMC used a Chrysler Dana 60 in that car. The Chrysler-sourced axle had LH lugs on the driver's side, but the AMC front hubs were RH thread on both. He had to buy two separate McGuard wheel lock kits, one for GM and one for Chrysler, to get three RH locks and one LH lock.

 

ah…I snapped more than one lug that way.
