Hello, I have the Thetford C400 Cassette but the flapper/green knob mechanism needs to be replaced. I have a Nucamp Tab 320s Boondock edition and the cassette loads on the "driver" side of the trailer. I am a bit confused since it seems like there is a Left side part and a right side part. Which one do I need to get? Thanks...
