So I got rearended yesterday....

[CastIron]

But thankfully it wasn't in my truck. I was in my daily driver and got hit while at a stop light. The damage doesn't look that bad, but now my neck is pretty sore. So this got me thinking.....

My truck is a 69 C1500, mostly original. If I had been driving that, my head would've probably went through the back window. So for most of the day I've been thinking about what I could do to my older vehicles to make them a little safer.
A newer style seat with a headrest immediately came to mind. Shoulder belts would be another thing. Maybe a more padded dash and padded steering wheel. There seems to be a lot of room for improvement.
I really prefer the old school look, but after the little incident yesterday I'm starting to think that maybe I should modernize some things just to protect myself and passengers. Does anybody want to share some of the ideas or upgrades we can make to our trucks to make them safer?
