Last time I did it, the pictures get submitted and they go to a committee to approve the application. You could try and call someone at ICBC who is involved with or on the committee to answer your questions... of submit your application and see what they say. I got rejected the first time, until I provided them with paperwork and photos from the 60's which showed the vehicle as it was. They listened, said ok and sent me an approval. (no extra application or fee)
