I got mine from ebay, from a user called Tamraz's Parts.

This hood is sweet. Just to compare. We got a fiberglass hood for my girlfriend's Dodge Charger -- it cost $1000 and it required tons, and I mean TONS of finishing/sanding/sealing before painting.
This GP hood for $440 came with a glass-like finish. Smooth and a perfect fit. Very strong too (mine was the BOLT ON version, not the PIN ON version in the link above which requires hood pins and doesn't come with the hood latch). The scoop is kinda high at 4" and it did interfere with the windshield, so we trimmed 1/4" off it and it's fine. Of course my hood is being modified to death right now but this is a damn fine product if you do get it. Plus I'd be jealous. Haha.
