Valiant tail light swap 67-69

so I have not found a good set of 70 lights but found a set of 71. Does anybody know iff 70 and 71 are the same? really like the idea of no back up lights in tail light. can always hide an led under valance. Sorry for all the questions but I know Darts and Barracudas much better than Valiants. Am getting ready to play with the 68 as the weather breaks and monsoon season ends. Thanks for the help.
