Seat Track Id Question

longarm said
Where are the part#'s on a set of bucket seat tracks located?
I looked at a set today and could not find any markings
or numbers at all.
These are 70-71 abody tracks.
Is there any foolproof way to tell?
Part numbers?
Thanks,
Carl

Not sure if this will help, but here are photos of 71-72 Dodge bucket seat runners. Left and right side of pass seat.
