Thanks to all for the replies. PasiR:Mine is a Glasstek. I got it at the Indy swap meet earlier this month. It has a flange around the bottom for mounting. Filled a couple low spots and blocked it down to get it straighter/smoother,but you will have to do that with any of them. Could have been a little bit thicker, but not flimsy either. I'm going to make it functional for extra ventilation and a little extra hood clearance. My air intakes are in the wheelwells.
