Can anyone help?

I am looking for 3 toggle clamps for a Daimler Dart SP250 which fix the soft top to the top of the windscreen. I have the chrome windscreen parts but not the 3 clamps which screw to the wooden front bar of the convertible hood.
Second hand or suggestions as to potential manufacturers welcome.

Warning, I've had an excruciating squeak for nearly two years and couldn't find the source around the driver's window or door. Eventually I discovered it was coming from the toggle fastener and a bit of cloth inside it has now given me peaceful motoring and I can hear the engine and exhaust again.

I purchased mine from Barry Thorne, he can be reached at barry@sp250.com
