My passenger has requested shoulder belts. I don't know if this is a commentary on my driving or that of my neighbors, but I figure it couldn't hurt. But I don't want to do major surgery on my truck. So my question is what is the minimum I need to do. It's a hardtop, 2A, 88". Here are photos of the door pillar, with and without the cover. It doesn't have a rollbar or anything like that.
