Front Wheel Stud

I suggest knocking one out and taking it to your local auto parts store to match them up. If you have some calipers (the measuring tool, not the brake part) then you can measure the size.

That being said, I have some that I knocked off and I measured it with my caliper and it came out to around .617 to .619 inches.

So these may work for you, but measure to be sure.
