need a source for 550 carb dust seal

During carb rebuild 2 of the 6 rubber seals cracked and broke into pieces.

Not having any luck finding carb dust seal # 92093-1033. Most sites have them listed as obsolete.
I'm awaiting a reply and clarification from Amazon as they have them listed for $ 42.96 "EACH".
Hoping there's other sources out there that have them available and reasonably priced.

Thanks

loudhvx has a motorcycle stuff page with a lot of info about the TK22 carburetors, but I don't recall seeing anything about those dust seals. If they're prohibitively expensive or not available, I would keep checking EB for new or used. maybe keep a lookout for a cheap used set of carbs or a carburetor body that still has them. In the mean time I would measure them to see if some sort of grommet or oil shaft seal might fit. OD x ID x thickness. I'd guess they're about 20mm x 10mm x 7mm or something like that. just eyeballing them.
