As it says on the tin peeps. Not advice on a wax but there's a coupe part from Mercado Livre which, according to Google translate and the website, they don't ship to the UK. If someone knows a contact out there then perhaps an arrangement can be made

Are you maybe asking for the rare 16v thermostat?
Best idea is to contact the seller directly. Regarding the thermostat, they can be found in other places, will be more expensive at first, but at least, there's no high shipping costs.

Unfortunately my Brazilian contact lives in the UK. For the next couple of weeks, at least.

(hehe I have one of those Brazilian thermostats with the removable stat module, still unused and in its original box. But it's not for sale )

Dang - I was hoping to be deliberately vague but you've flushed me out

386ka - pm sent.

I’ve got a contact in Brazil

Happy to email him and see if he can help. Pm me if you like
