I have had the 302 emblems for 2 years now....
to remove the original emblem, use dental floss and then some goo gone to get the sticker off.
a blow dryer might help if you haev trouble.
once you take it off, there will be 2 little holes. I aligned the emblem over the wholes.
If your paint is faded you rick showing the ghost of the original emblem in the paint
