My two cents........ I happen to love the chrome luggage racks! I have a '70 shaker Challenger that didn't come with one. I found another trunk lid and installed one anyway. I think it offsets the shaker as I have a stripe delete car (code"?") It's FE8 green with black vinyl top(was originally green top). The louvers are waaay cool , I just thought it would be way over doing it to also put the louvers on ?
