Wheel Stud Question

So we went to get new tires on my son's 66 Polara 2dr Hardtop yesterday and found out the jackwagon who had it before used some incorrect wheel studs, and JB Welded them in place. Needless to say the JB Weld did not hold up to the shops impact guns. So we have 3 loose studs in one wheel.

Speedway motors is local for me, which is super nice, but I am totally confused by the sizes and Knurl on the studs on their site. Does anyone know what size studs I should get?

Thanks in advance for...
