I did have the contact details for the company in France that make these but lost them and the replacement plate, in the AUGUS 2016 flood.
I did send a message to the Owners club to try and get the contact details again, but so far nothing.
If anybody can help with this I would appreciate it, please try a reply on my private e-mail which is on my contact page.
Thanks
Terry
To close this posting, I passed Terry the details and he has now obtained another chassis plate.
