Fiberglass/Carbon Fiber rear hatch

Checking to see if anyone would be interested---I cut the inside sheet metal out of the hatch to lighten it for a race car project---got it pretty light but it's very flimsy/distorts very easy. I figure once I get the lexan in it and bolt it to the car it'll be better, but there's no way I could mount a wing on it without going through to the floor/rear framerail.

I called Precesion Porsche Conversions who supply me fiberglass roofs/kits for the Boxsters we build and he said he could make one for less than a grand---probably closer to $700. I asked him what a hood would cost and he said about the same. He's not a production facility so he doesn't kick out ton's of hoods for $300 like you see on EBAY---but he'd be willing to do a couple of rear hatches for me...Any interest?
