Thanks man... the wood idea sounds like something feasible and pretty easy to do.... so I'll probably do that in the coming week. (Damn work getting in the way of my car projects!
)
And that's really what I was wondering abou the sheet metal. Because it kinda looks like there might be space inbetween the metal on the inside of the trunk and the exterior of the car, but as no-one's really said anything, I'll assume that it's a no-go.
