So I have found a oem low level rear spoiler to replace the rubbish one in my Zed. Any one know the best way to fit it? The tail gate has holes in it from what looks like the original spoiler and a long slot in the tailgate also. Do I just glue it on or is there special fixings available?

If it's a genuine OEM one there should be 4 threads from the bottom of the spoiler that correspond to the holes in the boot lid, you have to remove the inner boot trim to screw the nuts on. If it doesn't have them, then it's a fibreglass copy, this can be bonded on with tiger seal etc. I personally am going to a body shop to fit my one. Whack up a few pics just to be sure.

Hope this helps.
