so after being told by multiple mechanics that they couldn't do much except angle grind the bolts out of my rear wing, a 70 year old electrician took to it with a drill and got them out!
put the carbon wing on and the allen bolts wouldnt really go into it - got one in fine - rest just wanted to spin - so searched around my garage and picked up random screws and bolts here and there and put(forced) them in with a ratchet..
i just wanted it to be on already, secured firmly now! (probably impossible to remove)
