All our ballstuds are made by Lunsford, nice broached titanium pieces that they're known for. We have three lengths (refers to the length of thread, the shoulder and ball is the same for all of them), each come 2/pack:
XF 6170: 3/16"
XF 6171: 1/4"
XF 6172: 3/8"
Here's the quantities of each we provide in the K021 kit:
6170:3
6171:1
6172:3
That's 14 total ballstuds, which going through it in my head adds up to the number on the car.
