Try it and see if they fit. If not, cut the studs down a little to allow the hub cap to fit.

There is NO requirement the car have 3" studs. The NHRA rule is the studs have to extend through the face of the wheel at least the diameter of the stud (with washer installed if used). So a 1/2" stud must have at least 1/2" exposed once the wheel and washer is on (before installing the lug nuts).

If you ONLY run the steel wheels, the stock studs are adequate for racing. The longer studs are needed when aftermarket wheels are used which have a thicker center section.
