The foam was actually attached to the headliner material from the factory. Over the years the foam has basically dried out and turned to powder. There really is no way to just replace the foam. Any automotive interior shop should have a good selection of headliner material with a pretty good match color wise. Use 3m brand spray adhesive to attach the new material. Once you have tha adhesive on the two sides take a piece of masking tape and put it over the buttons . This will prevent the buttons from showing thru the new headliner. Robert VIN 3309
