Keep an eye out on ebay for the old MPC kit (1979?), it has the shaker hood. Built one back in high school, was a pretty good kit as I recall. I also built a 1/12 scale Monogram kit (1980?)for a buddy who had the real car back in the day, would be pretty cool to display that with your car at the shows.
BTW, I do the same thing with my 1970 Challenger RT/SE 440-6pack & the Monogram kit (converted from the T/A w/ some kit bashing & scratch built details), always get nice comments on both.
