VM carb pilot fuel screw o-ring source (& choke plunger o-ring)??

Robert Barr of cycleorings.com is on vacation in Yellowstone and unavailable to fill orders for his VM carb kits currently. I didn't realize that the Suzuki parts fiches don't even show the pilot fuel screws on the schematics, nor a part number. They also do not show a breakdown of the choke plunger being removed to show a part number for that o-ring. I suspected that I may be able to find that part number by looking up Kawasaki z1 fiches, but I haven't looked yet.

Does anyone have any other suggestions on where to source the fuel screw o-rings in particular?
 
Also I wanted to note again that in the fiches, there are 2 different part numbers for different 77-79 pilot air screw o-rings. I found that the smaller o-rings have fit all of the vm26 & vm22 550/750/1000 carbs that I have had my hands on so far. 13295-33010


The other larger o-rings in the photo on the left and right are spec'd for gs750c&ec pilot air screws, but are too large. This shares the same part number with the o-rings for the emulsion/bleeder tube that is between the pressed in needle jet & the main jet that threads into the fuel bowl end of the emulsion tube, as well as the float bowl drain screw o-rings being the same part number.

I have not found these yet to fit any VM air screws, so I think that is a typo as far as I can tell. Please correct me if wrong.

Pilot Fuel Adjusting Screw O-Ring. Used on Mikuni carbs fitted to:
KZ1000-A1/A2/B1/B2/B3/C1/C2 and other bikes - see below..

The fuel screws are the pilot circuit adjustment screws on the engine side of the carbs. Depending on the model, these are found directly under the carb or directly on top.

This part will aslo fit Suzuki GS750, GS850 and GS1000 models with Mikuni VM26 carbs.
NOTE: due to EPA/DOT emissions requirements, many of the fuel screws are covered with a small plug. Also, many models with the fuel screws do not show the part on the parts diagram, or there are no part numbers.as they were considered part of the sealed carb set.
