Here's a snip from the Standard carb kit catalog. Rock Auto has all of this in stock.

Thanks! After much research I found a video that said carb kits don't come with a choke pull off, which is another name for the vacuums break. This item can be ordered separately.

I would rebuild it with the kit components, and get a choke pull-off and a nitrophyl float to keep just in case. I've had to replace the float in my 73's 2100, but not the pull-off, yet.
Also keep a stock of accelerator pump diaphragms. I have to replace that about every 3 years.
