If the Patriot decal is period correct I think it points towards around 2004/5. Seem to remember these in the shop when I got my evo4. Also remember there was the 66 or +7 :?
I believe cyfa is correct, it's an '02/'03, it was around '02 they put that beefier shock mount on there with the plate underneath it. After '03 they beefed the shock mount up even more.
