Blaze's AE86

Ah, sounds familiar. I've had to do some foam transplants myself. If its really rotten, cut out a square bite of the bad foam and glue in a block of fresh foam, then cut it to shape with a bread knife (and perhaps fine tune with a kitchen grater or similar). If you have a thin foam or polyetser batting you can also cover the whole bolster with a layer of that to get the fabric to fill out.
