Bench seat hinge help

[Wgesnerjr]

Hello all,
I am ususally over on the 73-87 board but need yawl's help. I bought a bench seat from a 1995 pick-up to install into my 85. My wife wanted headrests so this was the most "cost-effective" option.

I have started to take it apart for cleaning, repair and, oh yeah...CLEANING! Smells really gross, like the last owner was a chain smoking septic tank worker with a chronic flatulence problem and a propensity for bean burritos!!!

I made the bone head move of not taking pictures of the hinge area before unbolting the back part. There is a bar and a weighted piece that fell out and now I can't figure out how they go back together. I think it has something to do with a lock for the back rest that activates if the truck decelerates suddenly.

Can anyone send some pics of the hinge of their bench seat. Specifically of the bar and weights? If not, maybe a illustration from a service manual would also work.

Here is a pic of what I have dubbed the "Seat of a thousand farts!"

Thanks in advance.
Jay
