I have never heard of a "disconnector spring". Look on this diagram and tell me what you are talking about

if you are talking about the clip that goes through the end of the disconnect pin, just put a small safety pin, or cotter pin in it and you will be all groovy. But if you must get an OEM clip, call Kingman and tell them the part number from the diagram and they will get it out to you asap.
