I am trying to finish my David Bradley Seeder (no fertilizer) attachment.

I am missing the 6T/12T (17018) and 6T (#17081) idler sprockets. Since I don't have the fertilizer, I don't need the 6T sprocket and can replace it with a bushing.

Let me know if you have a reliable source for either or both of these items.

--Cheers,
Brian
