actually honda also got rid of the bleeder screw on later DCs... i bought an OEM honda one from the dealer... had to special order it and i ordered both the bleeder screw and water neck. so i open the package and im like WTF!... i wasted $9 on the screw since i couldnt return a special order.
anyhow the water neck part number is still the same. its just revised. so even if you think you're ordering the old one... you'll get the new one.
