The T/A hood is more performance orientated .. designed for true cold-air induction (actually, its one of the all-time best factory muscle car hoods.. it works!)... weighs about 45pounds (improves handling with less front-end weight), although can be a change to keep super clean. Also, consider those wet/rainy days that you may get stuck in.. a bag or stuffing can block the rain. And.. softer hood springs are required, or else hold up bars which I have hinged across the core support.... also requires hood pins, as you know.
The metal RT hood is awesome and a true classic in design! I personally wouldn't paint it any matte color... looks great when its shiney! The metal RT hood is heavier at ~70-75 pounds.... reduces handling potential with the extra front-end weight. This metal RT hood is always weather resistant against rain, etc.
That black 72-4 with the custom seats, roll bar, etc.. do you know anything about it.. who owns it, general location??? Its really a cool lookin car!
