I've got a glasstek fiberglass hood on my 1992 Z28 that has a roughly 2" cowl. It's a "bolt on" hood with hinges, hood struts, etc. It even includes a latch. I'm planning to swap to a Harwood lift off hood and this one needs to find a good home. Glasstek charges $550 for these (as I remember) plus freight. I can't ship it, but if you can get to Ohio, or get someone to bring it back from the NASA nationals for you, I can get it there.
$350
There are some pics of the car in the "new to me z28" thread in the general forum. Once I get time, I'll attach one to this thread.
