Thanks for the responce, red58! I have seen that type jack here and there, I just did not realize the jack was used for so many years! As far as "usefull" it will be used more for looks, as my truck is a NAPCO. I'm sure I would have to "Block" the small screw or bottle jack. I have a small floor type jack in a carring case I take if out n about. But my curiosity has been satisfied! Thanks again!
