If you can get the hardware off fine. But not to worry if you can't. Get a big pot of boiling water going, then dump in a box of "RIT" clothes dye available at most grocrery stores. Read the package directions for the amount of water to be used with the box. If you have more than a couple of belts to dye , you might want to use two boxes. Throw the belts into the boiling dye water then turn off the heat and let the belts set for about an hour. After that, take them out and rinse them in cold water, then hang them up outside to dry. Bingo.......new seat belts.
