Wally Gee was really helpful - we emailed the photos and he came back the next day with the results - no charge!!

He also told us about factsheet 44a, which gives information on the changed requirements for importing vehicles, belonging to immigrants, that do not meet frontal impact or emissions standards. I have added the link below for anyone who may need it.
