Rallye Wheels - Help Needed

If they move at all, get some good quality penetrating oil at the base.

I've seen LH chrome nuts with hash marks perpendicular to the plane of the stud, halfway down each side, right at both sides of the point of the hex (wow, that was more complicated to describe than I thought).

Keep working them back and forth, each time going a little farther CW (loosey) and spray that penetrant every time you go a little farther.
