Any pics? Sounds cool! I've got a 71 R/T, FC7, N96, wing, 383, 4-speed, 3.91 axle package car... who knows if I'll ever get to work on it but I've wondered about louvers too. Mine isn't a vinyl top car so I don't think I'd do the louvers on it, but since yours has the top, I think I'd go for it if you like them
