curtain hooks for 1996 duetto

Hi all
some of the curatin hooks have broken, does anyone know where i can get them. i have looked on ebay but there are so many and it is difficult to tell the size in the photos.

i have tried all my local motorhome and caravan shops but they dont stock them.
thanks

I got some for my 2000 symbol direct from Auto-Sleepers.
They asked for details of the van so there were no problems.
Not cheap but simple and you get the right ones.

Good luck.

thank you
