It's been NLA for quite some time.... One of the hardest things to find in good condition is the beltline trim rubber. I found a set of NOS from a guy named Sevan. You can call to see if he's made any more buying trips to Germany. He has a 2002 Auto Repair place in Sun Valley CA. Shop # is 818-899-4999. Keep in mind, I barely know the guy, just bought my set including the metal off him on ebay a while ago. It was as described but I typically hate recommending anyone in case anything goes wrong, so proceed knowing that. Re: Substitute material, have not heard of any. Good Luck. -GB
