I have a '64 Plymouth Valiant 4-door. I need to know the wheel stud size to purchase new studs for the car. Also if you know where to purchase them please provide a link.

Thanks!

Stock size is 7/16" fine thread.

Stock studs were also left-hand thread on the left side of the car. This is lost on most of the tire techs these days - they often don't know to look for the "L" stamped on the end.
If you're replacing lugs, you might consider going to all right-hand threads for standardization.
Also, if you're replacing some of them, I suggest replacing all of them. They're closing in on 50 years of service.

ROCK AUTO has the right-hand studs.

By the way, welcome to the board! And congratulations on having the prettiest year Valiant they ever made!
