Mine had a piece of thin masonite with a hole cut out for the light, it was a bit broken, I made new ones out of 3mm MDF and glued some thin foam to it, seems to do the job. If you'd posted your request a couple of weeks ago, you would have had all the pics you could ever need, but see if these help, one shows the old stuff still in place, the other is with hood lining back in .
