Fiamma side awning panel - what size?

[CaliCrazy]

Hi, I want to buy just one side panel for the roll out awning just to keep off drafts. Makes cooking outside and sitting a bit easier. Narrowed it down to the Fiamma ones but it's a minefield as I'm unsure which awning I've got or what size I need. Can anyone help please?

First port of call is club shop, the Brandrup ones can be purchased individually.
