i need to replace my 2 spanner axle nuts that hold the hub on? the lock nut was cross threaded on and was a real treat to remove. does anyone know where these can be found? briefly checked ebay but no luck? its the lock nut with the little pin on the side and the lock nut. btw its a 74 k10 if that makes a difference. i am going to clean up the spindle threads also. thanks!
