I just bought a spoiler from a member on Facebook and when it came one of the bolts had snapped off, does anyone have a solution to this??

 

If it is installed like most mounting bolts are into fiber glass, drill into the broken bolt And take an easy out which has a reverse twist to it and screw it into the hole in the broken stud & it should screw out. then get a new mounting stud, apply some epoxy to it & screw it back into the spoiler & let set for 24 hrs to cure, then you should be good to go.
