Need Source for Wheel Studs

[Richard in Florida]

Here's a stud from a '54 Mercury rear axle. As you can see, it's in bad shape. I want to replace all 10 of them (5 per axle).

Are these studs common? By that I mean might they be used in other than '52 through '54 Ford and Mercury cars?

I want to find some USA axle studs, either NOS or modern that fit. No Chinese stuff. Any sources will be much appreciated.
