Craig, try your local mower shop, Outdoor King online shop, or do a search on the inet. Even try the web-site I gave you the other day. They are not high price items & should not be too hard to get. (I paid $5.00 for the clutch cone cork a few weeks back). Double check that you actually need them though. I assumed I needed the clutch cone cork, bought it & my "old" cork was the same thickness as the new (about 3 mm). Adhesive- Kwik- Grip (according to the fellow at my local mower shop). Just make sure you put the clutch cone cork in the correct way.
I hope this helps.
Cheers-Ross.
