brought a second hand rear spoiler to replace my old one as it had snapped at the mounting points. The new spoilers bolt holes are off by about half a cm or so on each side what can I do to fix this?
Like width ways? Maybe the spoiler is bowed a bit and needs a little pressure to on it to get them to line up?
The mounting bolt holes on non genuine/ aftermarket spoilers are different to genuine ones. Not sure how you fix it without getting a genuine one. If you drill new holes, makes sure you seal everything.
