I'm going to put in some 3 point rear seat belts into my cabrio, so that my kids can legally ride in the back with me. There's holes in the top corners of the firewall, and the two centre ones under the back seat. Anyone have any experience of fitting belts to a cabrio? It looks to me like it would be better to have a bracket at the back to turn the mount 90 degrees to the firewall.

Thanks!
