Gumball,
I agree with SaxBoy. That sounds like a job for a hip saxophone repair guy. I don't know your location but there is a sax guy near you that know's his stuff. I am pretty sure that the Conn instrument company is of businees but there are a lot of those horns still bouncing around.
I am quite sure your repair guy can tell you what's practical, what will work, and even if it's worth his and your time to mess with it. He may just say get a Yamaha.
You can't go wrong in taking it to an expert and getting the verdict.
regards,
Don
