My 65 Newport has 11" x 3" drums in front. It is a base model w/ auto trans, power brakes, and non-factory AC. I never heard of smaller shoes in the front, but who knows what the factory did. The cracked linings shown is not unusual. If plenty of thickness left, I just continue using like that and never had a problem. Since you guys have me worried on availability, I checked sources.
Rockauto lists for front drums:
Centric 12263045, 11" x 3", $49
Raybestos 1924R, 11" x 2.75", $82
Bendix PDR0019 for Police, taxi, tow package, $89
I recall my rears are 2.5", which rock mostly shows for their shoes. Perhaps the Raybestos above are actually rears. I jumped on some rear drums for my 65 Dart (rare) on rockauto, but received front drums (common). I trust Centric, since they give dimensions for all their drums. If your box says "Bendix Global", it will also say "made in China". Long ago, I worked for Bendix.
I post the best drawing I found of the Bendix drums below. The total width is 4.23", so I expect > 3" friction surface. Were there 3.5" wide shoes for police? BTW, for those challenged by unit conversions, search for "convert.exe" and it will solve all your problems.
rock shows many choices in shoes and fairly reasonable at $24-$40 per axle. The ones listed as 2" wide for rear is probably bogus info, which I see a lot there.
You won't be competing with me for these, since I still have a complete set of new drums I bought from a guy on Long Island, NY who had stacks of drums in his basement. That was long before ebay made that much easier.
