I have this one on my 2003 tundra. IMO it looks great - just like the company's photo and exactly like the T-rex except fewer vertical stabilizing bars (which is a good thing). When I was researching before I bought, I considered both the T-rex and the Stull. You can find the T-rex at
www.sporttrucking.com (see their add in Truckin' - it's there every month) but I recommend the Stull based on my own experience. My Stull grill is very heavy duty and of high quality IMO.
To install it requires that you remove the stock grill shell, then cut out the cross bars, leaving just the rim -- this is tricky. The billet grill then screws (or rivets) in place. The downsides are 1) you have to remove the hood release latch (b/c it mounts to the back of one of the cross bars) and 2) the grill makes a slight whistle right at 50 MPH (not above or below).
