I have not had to replace a hood...yet...I expect I will soon enough.
I have however just replaced my entire center console, and most of the dash plastics which I bought from http://rollmasters.com
All of which were damaged when a thief broke in and stole the electronics (AVIC-Z130BT stereo, Yaesu Ham radio, Police Scanner, and CB) they pried it all out with screwdrivers and brute force destroying all the center and some of the adjacent side pieces.
And a quick Google search for hoods popped up a couple sources. There are even some nifty carbon fiber ones out there (search for 03HMH24DOE-010C for example) Checked dealer stock on a whim earlier while picking up some small parts and the dealer here has 2 in stock...
