No worries! I have an MAS front spoiler for one of my cars too, I can't even remember which one at this point. It's super thin and has nothing you could use to mount it with that wouldn't involve more work, it would be a pain. So normally I agree with disparaging remarks about MAS parts, they're pretty flimsy.
But, in the case of their DC replica ductail spoiler, they hit it right on. In my opinion anyway, it's the best out of all the DC replica's and arguably better than the original.
