Roll down seat in ext cab wont stay in up position, there is like a latch to hold it in place on passenger side,but looks like it may be missing pieces.If you hit a bump or brake too quickly it flops down onto the bench part.I want to put my dogs back there but until I can make it stay in up position its not safe for them ...that seat is pretty heavy. Does anyone have a pic of the latch assembly so I can see what it is supposed to look like?

Seems like there should be a way to lock it up position,possible operator error on my part, I would think it should be spring loaded.
