5 Turbo 1 and 2 Turbo 2 Maxi bonnet vent dimensions

[Duncan Grier]

Trying to confirm the larger Renault turbo 2 maxi bonnet vent as per below picture for my 5....I know the standard size one.



Anyone lucky enough to have one they could measure or anyone able to help please?

Considering cutting up and extending a standard one to fit

For reference if useful

Stephen Dell would be my first try, he's got all sorts of stuff like this lying about.
