Seat question

I am wondering how to find out what the orginal seat in my car was? The previous owner installed a set of ver ugly Pontiac seats. The cars numbers come back as a 1971 Buick Skylark 350-2. It has a auto on the column and show no sign of having had a console or buckets. I pretty well know it was a bench, just wondering if there are more than one kind and if so how I can find out. Thank you.

 

Post the "TR-XXX" from the cowl plate. This will tell interior colour & style of seat.

 

Only 2 styles of bench seat.....standard and one with fold-down armrest.

 

Thanks to both of you, I will post the cowl number this afternoon when I get off work.
