Hi,

I think that if you measure the shoulder diameter on the old 7/16" lug nuts you will find that the shoulder diameter is around .680" +/-.........

There are many choices out there for racing shouldered lug nuts with a 1/2-20 thread and a .680" +/- shoulder........

On the other hand I could be completely wrong.......
