Ged,
Here are the pics I promised of the adaptors you need for the 1000. As I said before they consist of the two standard adaptors and what Abba Staands refer to as 10mm pins (10mm is the diameter of the middle pin that goes into the swing arm) you'll obviously need two of them.

If you give them a call and ask for Steve he should be able to sort them out for you.
Hope these links work, as I was having trouble adding images to the post tonight.
