Hi all,
first, possibly second, post and it has a note of desperation I'm afraid!
(Also posted the same on Mercedesclub.org)

Long story short we have a 2009 Viano destined to become a camper.
It turns out that the roof that is due to go on it was only made from 2014 onward.
Apparently the part numbers for the pre and post 2014 Viano roof are different, which raises the ugly possibility that there will be a hidden structural difference that prevents the correct fitting of this pop up roof.
I've photographed and measured our 2009 Viano roof and the roof of a 2019 van and find no significant difference whatsoever.
I won't post those photos as they are not any help with this next step.
The outer shell of the pop top would most likely fit fine.
It's the internal match that is in question.
It would be idiotic to cut into our van in hope, only to find it won't work, so I'm trying various channels to find out exactly what differences there are between the two part numbers.
As an "ex classic VW owner" I know that these part numbers are to be ignored at your peril!
Hoping someone can help move this along anyway.
Cheers.
 
Looking at yours it is pre facelift 639, I know quite a lot of people who have had pop tops fitted to there Vito/Vianos.. my friend actually runs a FB Group for Campers, that might help..
