I just wrote a comprehensive guide to all Haro hardware for Haro Bikes. It covers all of the 1980's frames, bikes etc. Plenty of new info derived from a lot of research. It references dates of manufacture, prototypes, differences between models; basically a mix of things I had for the collector site that didn't get published, along with new things that I recently found. I guess they will get it on the harobmx site at some point in the near future.
