Young kids in classic cars...what do you do?

I went thru this up here in Canada with my 67 dart
I added anchors in the back for rear facing car seats.
I also added lap belts for my own piece of mind.
I would let my daughter ride in the front seat on her booster because there is no air bag. It was a battle with a few people till the air bag answer.

Even one cop had an issue, till i mentioned the lack of air bags. The cop was not very old so he probably didnt know seat belts were invented
