My drivers side lugnuts were leftie on my '72.

Ignore some other posts, change them if you like; lug studs have a splined light- press fit and are meant to be easily serviceable since a tire may be removed dozens of times in the vehicles' lifetime. No swage fitting at all, just drive them out if they'll clear everything behind them, install new and torque to spec making sure that they're seated, with a retorque after 50 miles.

I agree. There was no problem at all changing them to all RH on my '69 Dart, or on my old '70 Road Runner.
