First the questions and then the long story 
This is a 69 Coronet 440 with barely any options. Non power drums all around.
1) Where do I measure to determine if I have 10 or 11s? If I measure the outer edges of the drum I'll easily be at 11. Do I measure there or across the inner drum surface?
2) Also I don't see a spring and hardware kit available at my local parts chains, where do you guys go for a good kit?
Now the whole story:
For awhile I've noticed when first setting off the rears, or maybe one rear, not always easy to tell, would lock with very light brake pressure. When that happens after a couple of stops I can't reproduce the issue, even on a dirt road. I thought maybe it was the combination of contamination and temperature of the shoes, so I pulled the drums to look today.
Driver's side seems worn but ok:
Pass side is another story, definitely was contaminated but not wet and I didn't see an active leak. Possibly the cylinder was changed a long time ago but the rest wasn't cleaned? Also the bottom most spring was broken which I think it the real issue. Is it possible that bottom spring situation is related to the adjuster when backing up and then it takes a few stops to get back in place? I figure its that or the contamination. Pics of the pass side mess:
The axle is blocking the full view of the broken spring so I highlighted what remains of the spring and where the other end likely went in the pic.
