if im not mistaken. i believe its held on with just 4 bolts. you have to pop the trunk and when you lift it up you will see these lil black circles at the top of the hatch. closest to you . put your finger nail under them and pull it out. once you have pulled all 4 out you have expose the bolts. get a socket that will fit and take it out. and do in reverse for your new wing. good luck
