3 point seat belt in a Terios


Hi all, I hope someone can help me. Smile
I have an '04 Terios, and have no plans to change him for some time, but the one thing I would love to change is the rear middle lap belt so I could get all the children in the back. Does anyone know if it is possible to convert to either a 3 point, or harness type seatbelt? I don't mind paying a reasonable amount of money as I intend on using my little car for some time.

Ignore the name btw [Jonah], I'm female! Biggrin

Many thanks if you can help, I couldn't see anything on the main Daihatsu website that might help me.
