I think I need to get new front springs for my '81 4x4. I noticed today that they are a little bent where the last leaf ends and it's just the one layer back to the shackle. Anybody have any suggestions about improvements? Or, should I just go with stock replacements. I'm not really interested in raising the truck up much higher. As I understand it I would have to get a different steering arm arrangement if I went higher. Ideas??
