I have a FACTORY, louver Road Runner, and it has regular polished trim just like all the others. But for those who would like to put them on their car, you have to do a lot of sanding and finishing to make them look right, no where near bolt on. And from what I remember most cars were body color except black and white cars, and maybe a couple of others. But even after all the work, a 71 with airgraber and louvers, you just can't beat that for looks.I've owned my car sense 74 and never get tried of looking at it.
