Pins only is not an option, they are just two small and too low value to even justify the packaging, there is the linked set and all spare plastic blades include the amount needed to install the blades. This generally is not a critical part, they were added many years later in production to make sure they don't work loose but they should stay in place in normal day to day use without this part. In general, I would buy the blades, they come with them and the blades wear and need replacement you will almost never need the clips for the care booster float in the set. US tunze.com order ship from the US, just be careful as I only get the orders if you are on the US page, following random google links for the part tends to be problematic as Google tends to pick up the UK and Scandanavian pages, go to Tunze.com, select USA, then search the parts on the website itself.
