How about these http://tinyurl.com/6ewml2 on eBay (item#330261307455), I just bought the last few sets today!
I got them for my kids bikes in the "on topic" late 1970s and early 1980s, but hadn't seen them since until I spotted them on a bike http://tinyurl.com/5cu4dy at the Bicycle Museum of America in New Bremen, OH, earlier in the year.
