Hi Francesco,
I fitted a bimini to my Classic 32 earlier this year and after lots of web searching ordered from these people : https://www.toldosonline.eu/en/p/biminitop-extension-dufour-36-cl
I wanted a bimini that didn't require drilling the deck and this was the only one that fitted the specification and appeared robust. I'm based in Nice so supply from Spain was straightforward and quite rapid. The product proved entirely satisfactory and is well made . Importantly, it fits well and looks good whether folded or open. I'm afraid I don't have pictures at the moment but those on the website are a good representation.
Cheers,
Martin
