Where can I find a drum brake hardware kit?

Well, right now I´m more lost than before starting this thread...
But hey, it´s better to learn then to buy wrong parts! :D

I will take apart one of the brakes later this week and check the metal frame/backing plate number.
But once again, I can´t go into a store and talk about this since I live in Sweden, and I am gonna buy new shoes, brake hardware and self-adjuster if it helps with buying a particular set :)

Grassy: PM sent.

Mattax and Oklacarcollecto: Great info, albeit a bit confusing when you don´t know exactly what everything is. Thanks for the help, I will be back with a FMS number :)
