I think the seats are the same. I bought a set from Sean last year, one was a earlier AD seat like a 50 or 51 and the other is a late 50's and they both match up to every other seat I have seen in other Suburbans either in person or on the 'net. My boss has a 57 Chevy Suburban and those seats look to be the same as what I saw in Tim's 'Burb this past June at Macungie.
