Never fear!
i can send you the replacement necks for a small fee of £8 each inc postage (my ingenious inventions take time to cook up and we all know time costs money anyhoo much cheaper than two half shells!)
i can send it and you can fix it, all you would need is a knife and some superglue, or araldite,(not poly cement) i find that superglue works well but there is a slight risk of the neck coming out if not fixed in properly, araldite is really strong and better suited. My feed neck is certainly as strong if not stronger than the previous feed necks (should hope so) (were they the new gem series poly carbonate ones as they don't appear to be as strong as the originals)
mail me if you're interested and i will send you my address.
