That's it? I mean I figured the old springs just are what they are. My bench seat is in really nice shape and intact, I'd prefer to have bolsters added to it so you don't slide away on aggressive turns, and get it more comfortable and not bouncy when you hit the smallest bump in the road.
I assumed bolstering it is out of the question though. 50 year old vinyl stretching? Even removing it and reinstalling it with standard foam could be risky....I would think.
