Bucket seats and tracks

I have a set of seat tracks from a parts stash. They have numbers on them but don't match anything I can find. Copy from a older post.


Got four seat tracks in a batch of parts. Was told maybe 69 Dart bench seat. The numbers on the tracks don't match anything I can find.
All four have two sets of numbers. 10918 on all four,
The other numbers are all different
