Lots of different car jacks out
there. In '31 it seemed that most of the cars came with a single
type that didn't change through the year. These are fairly easy to
find since they are small, stout and left over from the many , many cars
that went to the crusher during WWII. A complete kit includes the
jack, the folding arm, and the flat bar tire changer.
Tools are similar. The ones that came with the cars generally
weren't used too much and therefore a lot of them survived. This was
especially true since they could be used in the house or barn and
therefore didn't get thrown away very often..
