Many thanks to user niceoldman for the link to splash direct. Ordered the part required just now after hunting all day long.
As a side note, there must be a better way of designing these toilet seat fixings. The well nut approach seems to be flawed on a number of areas...
1) It is easy to break the screw thread of the moulded well nut
2) The material used to make the moulded part of the well nut, don't seem to last long
3) As pointed out previously, the swivel action force applied to the fixings when a person sits on the throne (seat) loosens the well nut with moderate use.
In short, not a great way to spend a Sunday [insert toilet gag here]
