I'm getting a little desperate in search of a locking nut for the exhaust of my Gravely with a Kohler 301 engine. The problem is that I live in Germany and the needed 1" NPT threaded locking nut (stainless steel) seems to be unknown on Europe. I've seen I can buy them on the US eBay but the shipping cost is horrendous, in the order of 30 - 100 USD for an item that cost less than 5$. Is there anybody out there who could buy two items, which then in an envelope and send them to me? Of course I will pay for it, e.g. via PayPal.
