finished trunks

I just slapped some carpet in mine and ran it up the insides of the fenders to give it a little more complete look. I would think you would pretty much just need to break out the cardboard and start making some test panels to figure out what you like. After that just make them in MDF or fiberglass or something and carpet them separately. I would try to just make stuff press fit or form fitting where you can so you can get it out easier and don't necessarily need to worry about making brackets or anything. I would love to see some pictures of finished trunks though, I'm sure there's lots of ideas out there.
