Expert Reply:
I am sorry Thomas but we do not have any replacement parts available for your Thetford Aria 19425 toilet. Really the only option I have for you is to replace it with the Thetford Aqua-Magic VI RV Toilet item # TH37SE.
The Thetford item # TH37SE installs on flanges that are as close as 7-5/8" from the wall. You'll want to verify this before ordering. It measures 20-3/8" tall x 15" wide x 17-7/8" deep.
I have linked a video below that will give you a brief review of the toilet and its features.

Hey Thomas, did you get a chance to check the flange distance for the Aqua-Magic VI toilet in your Monaco Diplomat? Knowing if that fit worked could really help others replacing older Thetford models.
