I think that 1969 prototype would have been pretty cool if it had been an option. Yes the hood is a bit too long, but by now we would have seen it all these years and been used to it. It only works on that type of hood. I love the shaker style hood scoop. I had a '79 Trans Am 400 4 speed and those all had a shaker hood scoop which was closed off at the back. After '72 they were closed off due to noise and/or fuel vapor emissions issues. The entire shaker air cleaner assembly was there and it wasn't just cosmetic. I used a Dremel tool to carefully open the back of the shaker and that thing sucked a ton of air. Sounded great with the t-roofs removed. Did not have the solenoid and the flap that opened and closed automatically, so I made a flat black aluminum plate that fit in the opening perfectly if I wanted to close it off manually during bad weather.
