Birel S6 body panels update

I’m not sure in what category to put this, but here it goes…

I have a Birel S6, and want to freshen it a little bit up. Newer panels.
Does anyone know whether the KG 506 or 507 panels will fit and/or whether I have to get newer mounting hardware?

Thanks

You will need new side crash bar and Nassau panel hardware for it to fit😁
