If your Insurance was arranged through a broker, simply ask them. If the Insurance is Comprehensive, as it probably is on such a new car, can they refuse to accept the claim, it was an accident after all. Check how any claim will affect your NCD, it might not make economic sense to even make a claim.
You could try to obtain the parts from a breaker, I realise that the car is new but even new cars get broken up after being in accidents.
