bucket seat hinge covers

I am looking for a set of bucket seat hinge covers for this 73 Dart Sport. I need both sides. The numbers on the one seat are: 3689026 and 3689027. Color is not a problem as they will be dyed. must be in good shape. I think these will fit 73-75 years. pics of the seat attached along with a pic of what I need. shipping to zip 41035. Thanks,Bill
