? About Bench Seat

[switchblades66]

Hey out there
I got a 66 step-side and i was wondering where to get and i don't know the name of it. It is the wire or piece of metal that goes from one side of the seat to the other and it is connected to the latch on the driver side to unlock the seat so you could move it forward or back. The one i got in my truck is broken and it does not look original it looks like someone jimmy rigged a thin piece but that is broken under the seat. And in order to move the seat i used the lever on the driver side and i have someone else to unlock it with a screw driver on the passenger side. I looked in lmc and they had everything else but that for the seat. I was thinking about finding one at a junk yard or making one. But if i could just buy one that would work better.
Any help or answers would be great!!!
thanks
