Hello. I recently acquired a "71 Barracuda" bumper jack at a tag sale and was wondering how to positively identify it? The hook has PN 2931101 / 93153 stamped into it and the jack itself has PATENT 3163925 on the stalk. The base is stamped U70.
Are there any good books or articles on Jack ID? I checked the archives here and didn't find to much.
Thanks!!
