Locating seat belt anchor bolts?

[b5cuda]

Looking for guidance on anchor bolt location for seatbelts.  The original footwell bolt hole and replacement footwell bolt hole are different (see pics).  The car is a '73 cuda but I don't care which location is correct for that year - just think it would be better for them to match.  Is there an advantage to one location over the other?

Top location picture is 1970 only, bottom picture is 1971-74. Two different types of seat belt retractors

Thanks Alan, appreciate the quick reply!  So in my case the ideal location probably comes down to which type of seat belt to use.  Much obliged!
