Does anyone know where I can buy used or reproduction black dash knobs? My white ones are all crumbling apart. I have tried looking online but I can't seem to find anyone who lists those parts at all. I would be totally fine with used ones as well.
No reproductions available, sadly.
Your best bet is to keep an eye out here in the 'parts for sale' forum, e.g.:

Also do a search frequently on eBay.
Hope you are patient, since it might well take years (like it did for me).
