have you a link for the ebay seals
have now found them on ebay and looking at the installation instructions I have been doing it wrong. I have always removed the bowl
Installation steps:
1. Shut off the water supply.
2. Depress the flush pedal to keep the flush bulb open.
3. Grasp the bottom of the old seal and pull towards you to remove it.
4. Clean the rim and bowl area where the old gasket was previously placed.
5. Release the flush pedal to let the flush bulb close.
6. Clean the rinse ball.
7. With the flush ball closed, place the new seal and press outward to ensure it is securely seated.
8. Reopen the flush ball and apply lubricant to the area where the gasket will contact the flush ball.
9. Open and close the rinse ball a few times and press down on the gasket to ensure it is properly seated.
10. Turn on the water supply, add water to the bowl and make sure there are no leaks
