Fiberglass hood mods... crazy?
Truck without cover means wet tools. lol jk
I think you should vent the area just in front of the firewall out the side of the fenders like a (pardon the french) trans am did in the 70's and 80's. Place them as low and as far to the rear as you can behind the wheel. I don't think too many people would be looking there on a 4 door car, so it wouldn't be that obvious, at least not as obvious as a hinged hood. Paint it body color and have some fun. Make sure to use ducting / tubing from the fender well to the vent or the air in the wheel well will mess this plan up.
What do you think?
