I think you should do whatever makes YOU happy. If you like the look and you have already bought them then by all means put them on. I like them both ways. It is refreshing to see a 71 without them but at the same time nothing says 71 'Cuda like billboards. With your color combination I think it would make a huge visual impact with them on. I mean we see 70 and 71 cars mixing up stripes, 72-74 Barracudas with hockey sticks, 72-74 Challengers with every variation of R/T stripe so its not a big deal at all to see a 71 'Cuda with a stripe that was actually offered on it.
