Buying a $4 spring remover/installer makes doing the rear brakes so much easier than using a scredriver and vicegrips, so consider that next time you are in the tool isle at Autozone.
Do one side at a time the first time so you have the other side for reference. Pay close attention to the spring that falls on the ground and you wonder where "THAT" goes. Also pay attention to the adjuster orientation and how the "rachet lever deally" works and how the loose spring fits on it.
Adjust the brakes out until you can just get the drums back on. This will give you a good starting point and may give you a perfect pedal and no drag, if you are lucky.
