Ben,
Your ever changing story is annoying, I hope others can feel my frustrations!!
You said you could see from my pics the baseplate you supplied did not fit! You said you had another good one and would test fit it. You are now saying you want mine back to test fit, test fit it for what? My pics are quite clear.
I asked you to supply pics of the test fitted base plate on here, the new one you are going to send, not unreasonable I feel, I did as you asked and posted pics of the appaling fit of the base plate I received on here.
Please do as you said you would and test fit another base plate to ensure the one I get will fit properly. If you can't be bothered/ wont do this please say and I will just send the whole spoiler back.
