Confused on Spring kit 68 dart

Hello all i'm new to the forums and i'm asking for help i have sum knowledge on theses cars i'm just having a issue with the drums i understand that Napa should have the correct spring kit but i cant locate it, Auto zone has many different types but none fit the car it's a 1968 Dodge Dart with a 5.2 318 in it.

I put the engine in it and along with the tranny need to fix a small transmission leak that would cause it to leak when the trans fluid is hot but before i fix that i want new brakes all the way around working on the front atm. heres a picture to better describe what im asking. I need a spring kit that will work for a 10 inch drums and shoes.
