Roof card needed

[tacoma]

Hi, i have found my way over fromt he TVR area and really need some help; and i promise this is not a joke!!
My springer puppy was left in car for 20 minutes during a recent beach recce and when i returned he had eaten a sizeable chunk of the roof card!!

I have been told that a replacement will "cost a fortune" and i haven't got one!

Look, i hate people who leave their dogs in the car too but we all do it occassionally, so can you help?
