I have gone to aluminum since black isn't avail anymore. It's more rigid to compress the sealing oring with, so I figure it's an upgrade.
I dn't think Honda uses the clear and black zinc interchangeably for a given part number. bolts that end in 07, like this as far as I have documented are black, and 00 are zinc.
