i think there may be stock of the spats, but post to the U.S. would be mental, spares for all the models are available, spares stock is up to the importer, but bigger items would have to be ordered, problem with spares are, you end up with lots of expensive bits you cannot sell, YT has lots of parts, cowls, canopys, decks, etc etc, that have cost a fortune, and are obsolete, its not always easy to stock lots of parts, to my knowledge, we have never been asked for the pants off the stuka, mine are still in good condition, but, i must admit, i did line them out with glass tape,on the front bulbous part as i do with every type of spat from any model from any maker i have known, just simply stippled in with epoxy, uses no weight, and adds strength, and takes 20 minutes,
