Thanks guys. I know of one car that I believe has the original springs (it's an original car) and they are 4-leaf. I knew the 4-leaf was the HD option, but I was curious about it since the LDO option list said "handling package". Is that was just the sway bar then or something completely different? Why is it listed under interior? I've seen many LDOs with the deep shag, but I figured the LDO option list would say something other than cut pile.
