Your right but the new tan trim I noticed are a little shorter than the older red ones and the red might fit better and be easier to work with on the older C style nozzle. I agree if the tan ones will work that would be a better way to go. I have never replaced the trim on a C style nozzle before, so I'm just trying to give some options. I also did not find the new ones on the Kirby needs website although I'm sure there might be other places to find them.
