Ficklin was bought out by Unverferth Group of companies. The new company is known as Alliance Ag products they carry the Top Air Sprayers and the Parker Carts. The Ficklin name is no more. Talk to one of these companies or a dealer of these products and I am sure they can get you what you need.
hey pbutler, if your still curious to this question i'll ask Steve ficklin who was the owner of teh company. he lives/farms and produced the grain carts and wagons in my town and still has a stockpile of OEM flighting, gearboxes, etc. that he hasnt sold yet.
