Seat Trim for '63 Dart

I have a 63 Dart 170 and mine doesn't have covers at all. It only has black painted steel hinge. The upper back upholstery covers the upper half of the pivot.

I did a google search on 63 Darts and all I found were the same, 170, 270 and vert. I did find a cover shown but it was on a 63 Valiant. I found bench seat pics of 4 different 63 Darts and all were the same. My seat looks like crap right now but is original. Car is from Nevada and only has 50,000original miles. Getting interior done in the next few weeks. No indication there was ever any covers on the hinges.

Just looked at the ones on classic industries. I wonder if they are supposed to be for the middle between the seats. Going to have to have a look when I get home now. Can't see how they would work on the outside pivots
