Was going to order a set of McGard locking lug nuts, but apparently there are different styles

MCGARD 24215 Cone Seat; Exposed Style
MCGARD 24019 Cone Seat; Under Hub Cap
MCGARD 25115 Tuner Style; Cone Sea

I've got the Lariat appearance package so it came with the 20" wheels if it makes a difference. Without pulling a lug nut, I could measure about 3/4" of lug, which makes me think it is the Cone Seat; Under Hub Cap, but unsure.

 

24215 will be as close to factory as possible.

The under hub cap one is an open end lug nut lock

The tuner style is similar to the exposed style but thinner to fit aftermarket wheels.
