Adding Bronze Bushings to Ductile Iron Rockers

I don't think anyone here is saying you cannot run them unbushed. That's for those who are arguing. All we're saying is, if you're building from the ground up, my God, this is 2024. We all know the benefits of bronze bushed rockers and if you don't, read up. Just because you did it for forty years forty years ago, doesn't mean there's not a better way now. If you're building from the ground up, why on Earth wouldn't you want to do it if you can afford to?
