XC90 Dog Guard - retrofitting?

[Volvo321]

Hello everyone,

Has anyone had an experience putting the new (2015+) luggage grill/boot divider/dog gate into the older post-facelift (2007 - 2015) 1st generation XC90? Have they got similar enough fittings in the back for it to work or am I messing up their safety/crash test guarantee by not sticking with the right accessories?

My reason for thinking about this is two fold:
1. Safety. I want to keep the kids/luggage as safe as possible and expect Volvo are constantly improving their products...therefore 2nd gen dog guards may be more refined in their safety protection. For example, the crumple zone has been updated in the 2nd gen boot divider.
2. Availability. I can't actually find Volvo dog gate for the 1st generation XC90, only the luggage grill/divider.
