This is the page you can use to determine what kit to buy.
And this info from his site: "The Rochester 1 barrel used a small metal tag attached to one of the float bowl screws for identification. When the tag is missing, check the bottom of the mounting pad. If you find 4 numbers add 700 to the front of the 4 numbers and that will give you the carburetor number.
Email Mike's Carburetors and he will set you straight.
Mike Carburetors has a video on your B model. It shows disassembly and assembly. Everything you want to know is in the video.
This is a MUST WATCH video.
My 2¢ about that website.
If your "carb tag" is missing, you should not be confident that the 4 numbers
on the bottom of the base (throttle body) is your carb number.
By adding 700 to those numbers will only tell you the carb #
that the throttle body was originally married to.
Through the years all parts such as air horns, float bowls, etc. have been mixed & matched.
You can buy the same carb kit for $5 to $10 cheaper if you shop around.
Some offer free shipping.
Also, the kit appears to have the incorrect base gasket. Vacuum hole/slot in the wrong location.
As he notes in his video.
With all due respect, the video is a poor example
on how to disassemble & assemble the Rochester 1 BBL.
I have many concerns, here are a few.
Although I have rebuilt a number of these carbs, I am not a professional or an expert.
But....I would NEVER EVER use a pair of pliers to remove a stuck brass "power piston",
especially trying to remove it dry, without putting any "juice" on it.
The newer pistons are hollow and have a tiny bleed hole in that must be clear.
"air bleed power piston"No need to mark/score/damage the choke plate.
There should be a "RP" on the plate.
"RP" must face outwards with the choke closed.
In the video, even though he marked the plate, he still was confused on how to assemble it.
Just look for the "RP".
If you remove the plate on the throttle body
make sure you know what you are doing.
There are holes in the throttle body that MUST line up with the holes in the plate.
Advice from General Motors And NEVER EVER use a metal object or pry the plate into position.
And don't crank down one screw first and hope everything is in position.
I turned the video off after he again became confused
when he didn't know why the throttle base gasket hole/slot didn't line up.
He said he would have to do some further research.
We all do thinks differently,
So again, it's just my 2¢.....
