Removal of stock spoiler

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

You are correct.. it's just four bolts under there.. i believe (if memory serves correctly) it's Metric 6.

My preferred method is backing up to the garage with the decklid up and a larger TV in the back of the cougar. My garage and roof eaves are just high enough to clip/shear the spoiler without damagin the deck lid too much. had to replace the lid...1 bolt tore through instead of breaking at the spoiler. oops, I never claimed to be the smartest person out there!
