4″ Bolt Pattern 10″ Brake Drums

Looking desperately for a set of brake drums for 65 Dart GT
The Rear drums are for 10" brakes and having a tuff time finding supply.
Not even sure I am asking the correct way. I do get told from suppliers that the car should have 9" according to the catalog they use and I try to convince them that it is indeed 10" brakes. I have a set of 9's from my donor car so I know for sure 9 is not what I am looking for.

Help much appreciated!
