I don't know of anyplace that sells them aftermarket, or NOS. I was looking for a pair as well until very recently. Had never seen them with the exception of a few pictures on here, and was hunting for a blue set. Don't know how many red, tan and brown sets passed through eBay and at a very high price, but eventually those all but disappeared as well with a single panel being sold here or there. I know they were made in blue, saw one listed on occasion, but never a pair (even listed separate at same time). Gave up on getting blue. Gave up on getting a set period, but got lucky with a red set off a fellow forum member, planning to have them recovered by a local shop. My suggestion would be to hit up local yards, and watch the forums for people parting out a first gen and ask about the panels. May not find black but if you find a set you could always have them recovered or die them black.
