Cascavel Alloy wheel centre cap size

[Mr T]

Hello helpful people.

Can anyone confirm the size of the centre cap required to snugly fit in the middle of a Cascavel alloy?
Ideally genuine part number would be great.

I think it is either a 65mm or 70mm dia but would like someone to confirm as there seems to be both sizes listed for a T5/T6 alloy wheel.

TIA
