I don't quite know what you're measuring. It's too variable with the chainstays at an angle to get a meaningful comparison.
Mine comes out right at 126mm (4.965 inches) inside the dropouts just above where the locknuts marks are.
How about some pictures ? 120mm is not right. Do you get 120mm at all areas of the dropout, or is one maybe bent in so they're not parallel ?
Those rear triangles are not easily deformed.
