70 and up seat track help

I have a few duster with buckets seats but all inner are installed both ways. One way has to be wrong. None of them are untouched so I cannot compare and say whats correct. I have a bunch of passenger side seat tracks. All are the same as above pictures. Hard to say I have 5 passenger side outers and 5 driver side inners. Does anyone have a car that was never touched?
