Where can I find a replacement? I've looked every where and I could not find them.

Megaaudio has the grey foam rings too. The ones for the Fostex TH-900 fit perfectly, they are identical to the original Denon ones. Catalogue number of the component: 1416449811. Email Megaaudio, as it's not listed on the page: but they have them and will be glad to sell them. 2 years ago, they went for 27 EUR per pair.
