Ever try to buy a part only to find out it's part of an expensive assembly and not available separately? Yeah, me too. Sometimes Honda doesn't list a part separately but it is available for a different or older Honda. Sometimes part numbers for a separate part are listed in technical service bulletins, but the parts lookup is never updated. In any case here are some of compiled, I will add more to this when I find more.
