I have an 01 and there is a place on the back wall where you can clip the strap. I looked the other day (due to second kid arriving

) and saw one.
I pulled the back of the rear seat forward and on the passenger side there was a place for the latch about halfway up. Looks like you have to hook the strap, put the seat back then pull it tight.
Cheers
I'd post a pic but seems this site doesn't allow pics to be attached
