Was putting new carpet and headliner in the 76 Volare this last weekend and when I went to reinstall the passenger seat belt, I noticed the weighted pendulum for the locking mechanism was just lying there. What are my options? I'm assuming gluing the plastic pendulum piece that snapped is not advisable. So is that piece replaceable (doesn't look like it's meant to be opened up and worked on)? I'm assuming the best approach is either to buy a used direct replacement from a parts car or buy a new universal retro seat belt and try to force it (but it will be new).
