-New updated floor jack base plate - the fourth picture shows the updated base plate
for newer floor jacks that bolt together, we still include a pin that
presses into the base for older jacks with 1 3/16" pins. There are two
styles of bolt on base plates, this will fit one of those, the other
style will be added soon. This works for floor jacks that have a lip
with the base removed. To check your jack, remove the base and look at
the jack, if there is a lip sticking up your good, if the jack is flat
then it won't work yet.
