Are the seatbacks interchangeable passenger/driver?

[adc]

Yesterday as I was detailing the interior, I had the most unpleasant surprise - my finger went right through the leather on the seatback driver side! Obviously it was already cracked in that spot and I should have been more careful. Lesson learned.

Now I'm looking at seats on ebay, and found a reasonable set with the passenger seat in good condition. My question is, are the seat backs interchangeable between driver and passenger?

Any information would be greatly appreciated!
