Referencing a model in a drawing

So I made the mistake of referencing a different model in a drawing and then saving it. The reason it saved with no errors and rebuilt properly was because it is the same part as the one I intended to reference the only difference are two threaded holes that make it a configuration of the part. All the dims were the same and SW just recognized the extra two holes and called them out . How can I just re-save the drawing with it referencing the correct configuration of the part? I don't want to have to delete and start over.

Thanks!
