Hi Melonfish
Try contacting Endicotts. They will probably sell you one of the ones they use in their conversions.
Or you could try here... http://ukkitmonster.com/product_info.php?products_id=893&osCsid=ea3ec8aeb1093cc99f4b3e6446599987. They sell zips that are used in British Army sleeping bags.
Regards
Phill
