69 Seat bracket.. little help

[~Whitey~]

In the picture below is the drivers side seat bracket on top and passenger side on bottom.

Question: Where the rod connects is a little spring and metal piece in which the spring sets behind. I don't have one on the outside of the Passenger bracket but it seems like it should have one. Can anyone verify this and also if I do need one, is there anywhere that sells them.

Thanks in advance
