Stradale OEM replacement diffuser

does anyone know where to get OEM replacement rear diffuser for the stradale? I checked Ricambi's site and it cost almost $1400 per side and you have to get both sides.... are you kidding me? Spoke with Brandon in Australia but he told me his replicas are only good on regular 360 bumpers not a OEM strad bumper..... I am looking for just the right side (Passenger side on US car) does anyone have one or know where I can get one fore resonable price?
Thanks for your help.

 

Don't see it at their site, maybe they don't make it any more

 

I did, spoke with mike Oakley and they only make the add on fins

 

This would be a good business for someone or some company.
Spoke with Rocco at classic coach yesterday and he mention that so many stradale and challenge car owners have busted diffusers from being rear ended or simply getting off the trailer. Looks like the aftermarket ones are only good for the regular 360 bumpers so at this time stradale owners are stuck spending $2800 for a pair.
