No probs!
As for the van comment, providing you've still got the seat belts in place then technically its only a temporary change..
I took the interior out of my old Honda CRX back in the day to find a water leak, it was out for a good 3 to 4 weeks and no one ever said anything.. Even in the name times I was pulled over the old bill didnt ask (that car used to attract the police like god knows what!)
To be on the safe side Id just call them?
