Wow, that's big for front drums. My C60 has 14x2 1/2" drums and they're well past spec. The local truck place can line the shoes with double thickness linings to make them the same size as the enlarged drum, however I too have been looking for a set of new drums. I'm starting to look more seriously at converting to disc, there seem to be more options out there nowadays.
