I agree, do it right, post on the v6 board and offer to swap your trunk and spoiler for a 6er trunk plus have them give you some cash. Only downside, hope they have paint in good shape that will match up to yours. Would suck to have a lazer red car for example and switch on a pinkish faded trunk. You could fill them yourself, maybe bondo or fiberglass. But if you do that and you have it painted, you always run a risk of the filler cracking if you an not skilled in it.
