Cattfish I got the tonneau cover aftermarket from a place in Windsor Ontario called Vehicle Ventures. It cost me $1200 Canadian and that included having it shipped, painted, and installed. Oh yeah and that also includes the tax. It's a bit pricey but will last forever. It's steel with a gelcoat and fibreglass reinforcements so it won't warp or crack, and also has a nice smooth surface. Only downside was it took 6 weeks to deliver.
The lid is made by a company called Gemtop, and is called a GT Classic.
The sub box was designed by me and I had a friend (cabinet maker) help bring the drawings to life. This guy did an awesome job, beautiful joints that maximized the inside volume and still made it strong as hell in case I had one of my heavier friends sit on it....its all 3/4" MDF
CynicX, I got the billet bowtie from www.truckperformance.com
It is on sale for something like $14 USD for brushed and $25 or so for the polished. Excellent deal, and really nice product, you should check it out !
