73 Bucket Seat Tracks for 72

John, I'm guessing that Legendary Interiors was referring to the 72 versus 73 seats themselves & not the tracks.

The seats are quite a bit different. Soft cover backs on 73s, hard cover backs on 72s. Seat release mechanism is also different between them.

The tracks are virtually the same as mentioned & if there are ANY differences they're subtle...

You might want to call them back just to ease your mind :)
