1969 CA77 (Late Model) float valve set OEM part

[quidger]

I own a 1969 CA77. I want to order an OEM float valve set but I’ve run into an issue identifying the part #. All of the Honda dealers’ parts fiche’s only show part #’s for the “early models”, 1961-1963. The 1964- 1969 models are considered “late models “. The part # that in find online for the early models is 16011-375-004 and it’s available through my Honda dealer.
Bill Silver’s Parts List shows the round bowl Keihin , which would be from early models, as #16125-259-004. I am assuming that Silver’s part number is correct so I’m wondering if the 16011-375-004 is actually the correct part for the late models. The 16011-375-004 replacement part is 2.5 mm and the seat in my 1969 carb is marked 2.5.
Can anyone with knowledge about this, please share your information .
Thanks
