1966 - 650 ​Carburetor numbers: replacement compatibility

[Mercproject]

I have a 1966 650, ser # 1869630 (Canadian) 4 cylinder.
The numbers on the top carb are KC54T (I can’t see the numbers on the bottom one)
(from the parts manual: Part # A-1335-2474, KC-5A)

I am considering the purchase of a spare set and have a couple of options.
One set is from a 1967 650 ser #2122557.
(Part #1335-3016 - KC5BT and KC5B).

and the other is from a 1967: Part # 1335-3016, KC5B

I am ASSUMING these replacement carbs will work on my motor.
Can anyone confirm or deny this assumption?

What do I have to look for in the way of replacements, exact number match only?

Thank you in advance.

Nothing goes wrong with these carburetors that would warrant replacing them.---They are very simple and easy to repair / clean.-----Your location is ?

Thank you for the quick reply.

That is what I needed to hear.

I'll just clean them and give them a kit when the time comes.

These are an excellent smooth running motor.----Have one of those 66 models myself along with a few others from the 60's.--------Many parts are available here in Ontario.
