Replacement windows Fleetwood symphony

Hi, looking for some help/guidance. We own a 2007 Fleetwood Symphony Sonata, only had it a year but it's in brilliant condition and already made several great holidays. We're all booked up for late August and some thieving little ****** has broken in and stolen 6 windows.

Obviously Fleetwood ceased trading a long time ago, so getting hold of replacement windows is a challenge. To get replacement made I need to give exact sizes, for a broken window this is simple- measure it. As I haven't got the windows I can only measure the apertures.

Does anybody have the same van who could provide the measurements of the windows? or does anybody know a breakers that are likely to have some Fleetwood windows for sale?

thanks

Stuart
