I'm pretty sure you will find trying to repair one of the Thetford Style II toilets will be a waste of time and money for parts. I attempted to repair our original one years ago, had all the proper parts, and ended up tossing everything and installed a Dometic 310, and this was and is a very reliable toilet compared to the troublesome Thetford. Most of these, including the Dometic, are really throw away toilets when they finally fail or wear out.
