Remove one of the lug nuts and take it with you to a tire/wheel shop or an O'reilly Auto, Autozone, etc. They can match it up and make sure the length is correct for your wheels. And yes, 1/2"X20 (1/2" diameter stud By 20 threads per inch) is correct.

Okay...thank you for responding...I bought 20 from a guy on ebay not a lot of money but, in his description he said they would fit a 1973 Roadrunner wheel...too small in diameter { like my brain at times }...Marla

Also to add, the length of your current ones seems a bit short, and also the "seat" style is "conical"
