Ha! Like $1.50 from a certain online dealer who shall remain nameless because they wouldn't ship to my work address. So I went to my local green bike dealer: out of business. Went to the big local dealer who has since taken on a Kaw franchise, had to pay for parking, went through hell with the counter person, and finally got a hold of two. (One for the next time to avoid this ordeal.) $6 and change a piece! Sorry, this probably belongs in the flame forum.
No wonder I just used safety wire and silicone on my previous front sprocket.
