Absolutely you could order louvers without a vinyl top... There was a note in the salemens pocket guide that confused the issue.. What it was intended to mean is if a vinyl top was ordered the top had to be black... The only car I know of locally coded for louvers is a FY1 T/.A without a vinyl top..
No textured mouldings for Challengers, No black moulding either...
The textured mouldings came on most Cuda's with louvers but not all, the textured mouldings also came on most Gran Coupe Cuda's/Barracuda's but not all.... About as clear as mud huh?
