Which size drums on 69 Dart? And some other brake questions.

The brakes were done not that many miles (a few thousand), but many many many years ago. So the shoes are in pretty good shape. It didn't really look like brake fluid was getting on them. But maybe I shouldn't be lazy about it.
Yeah, don't be lazy- these are your brakes after all. Another $20 to make sure two tons of steel will actually stop is a good investment in my book.
