Taking the bolt apart.......... Have you heard the phrase '......if it ain't broke, don't fix it'? That applies here.
Read up in an earlier thread to ascertain a) that YOUR mismatched bolt fits YOUR rifle correctly and b) if it all working exactly as it should be. If it is, do nothing else except perhaps do what a zillion Armourers have been doing since Enfields hit their work benches. File out the old and re-number.
