Bench seat mount questions

[Zoomin]

I dropped off my bench seat to get it reupholstered, and I picked it disassembled - the mounts were off, along with the spring and latch release cable. So my questions are:

1. How many springs are there supposed to be that assist the bench when moving it along the track? I only have one, so I'm hoping that's all there is.

2. Where does the spring attach? Does it attach to the drivers side or passenger side? Where does it hook on the upper and lower mounts?

Seems like it sould be a simple thing to figure out. I messed with it for a while, but due to the length of the spring, nothing seems to line up right.

Thanks!
