Delco Remy or Delphi 125 amp. Similar to AD 230 but 7 mm larger. The kits are the same, so it’s not really necessary to measure the difference. Some AD237’s like on Aurora have an exposed metal ring in the middle which is approx. 33mm wide. The Aurora is a common alternator failure due to oil leaks. Other versions with the thin line between the 2 aluminum halves are found mostly on Park Avenue or Bonneville. Both styles have the Delco typical 4 pin plugs.
Kit includes : 2 bearings, 2 brushes, voltage regulator.
