Which is the right number?
Does anyone have pictures of the correct vacuum + centrifugal distributor off a '57 312?
As cast/stamped on the distributer FEJ 12127 A2 is correct for the 57 Thunderbird single carb engine.
Also as cast/stamped on the distributer FEK 12127 B2 is correct for the 57 Thunderbird single carb engine.
