Hello everyone! Nice to meet you!

I drive a JDM 2-door Levin. I want to use it as a family car, and I feel the JDM Two-point seat belts are a bit unsafe. I would like to upgrade to three-point type seat belts, and read that in Australia rear 3-point type belts were mandatory.

How do you guys source them? Here in Japan, they are impossible to find. New ones are out of stock, and I couldn't find any second-hand ones. Do you know if belts from other models may fit?

I can do metalwork, so minor changes to the body shouldn't be a problem.

If I get the original ones, I will also need the C pillar trim, correct (or I drill my trim piece)? Anything else I should look out for?

Also, I have read that your ADM 86s came with child seat restraint brackets in the trunk. I have never seen these before and can't imagine how they work (in my country, we usually only use the seat belts). Do you mind explaining it to me?

Thanks a lot, everyone! I also wanted to attach a picture of my Levin, but I get the error message "86.jpg: Unable to move/copy file". Anyway, here is a linked picture!
