I wouldn't throw the jack away either. They aren't the safest way to jack up the car, but you should hold onto one even if you just keep it for show purposes. Chrysler stopped using the reverse thread lug-nuts during the 70s. Any 80s or 90s Imperial and probably some mid-70s Imps and NYBs will be the same on both sides. Many of the earlier models had them changed over the years. Not knowing always makes changing a tire for the first time an adventure.

I think this began in the '40s, possibly earlier. _________________________________________________________________ Rethink your business approach for the new year with the helpful tips here. http://special.msn.com/bcentral/prep04.armx
