T-rex phantom billet grill p/n 20790 but not sure if that is still in production. You can also buy one from a larger vehicle and cut it down to fit.
Belltech drop spindle is p/n 2005
Headlight is a standard 4x6 size, use a conversion lamp that uses a standard H4 bulb such as these: http://www.truckshop.com/home.php?cat=515
Another option for headlights is to use 1987-1990 Caprice one-piece headlamps, that was a popular mod in the late 80s and early 90s.
I've seen clear corners, but don't know any current source for them. Try checking ebay they might pop up occasionally. You could shave the corners and do something custom with the bumper, since the stock one is 3 piece you could cut that up and shave it or swap a Toyota bumper.
