Clubman estate rear seat belts

[gtidreamer]

Folks, any advice on fitting rear seat belts into a clubman estate would be very helpful please. Limited info from a google search but there does appear to be scope to engineer a solution. Ideally I want to squeeze 3 kids into it.

The last estate shells came with mounts for 2 lap belts in the rear, will try and photo mine on my project shell. Geoff
