60' Comet Radio stem nuts

[19Spaceage60]

can someone please tell me the size of those radio stem nuts? It looks to be about 5/8th?
I've found a place that sells em, but they need to know the size and threads?

Anyone know?

Thanks -

They should be a 1/2 " X 20 (UNF) fine thread about an 1/8 inch thick. I think it might take four of them two behind the dash to set the height and two to tighten the Radio down. Many of the Radio's also had a bracket mounted to support the rear too. Good luck

Thanks again!
