The correct replacement flush ball assembly for the Dometic Full Timer toilet you have 321 is the part # DOM65FR.

I have a mod 321 dometic that needs the ball flush. I also need the nylon anchors that go in the porcelain.

@PeterL The flush ball assembly you'd need is the part # DOM65FR. This kit comes with fasteners that you can see in the product pictures. Does it come with the ones you need?

@JamesonC no sir. I need the ones from bowl to base. Nylon anchor/toggle anchor bolts.

@PeterL I believe what you are looking for is the 385311009 which is a part we don't carry at this time. I can look into having that part added if you'd like though. I hate to send you somewhere else but if you wanted to search that part number and see if you can pull it up and tell if that's the parts you need.
