Another authentic detail on Dan's conversions is the door frame plugs. These wood plugs cover the countersunk screws fastening the wood corner braces to the doorjamb. In case you were wondering, this is another detail done by Ford in 1932. Once sanded, stained, and varnished, it's almost invisible--unless you're looking for it. These small details, done for accuracy, are what make these conversions so successful.
