Since I wanted to keep the bench seat but still wanted more room I looked for options. When I took my seat out to installed seat belts I noticed how thick the back cushion was. With the back cushion out I had all sorts of room so I had a guy take the springs right out of the seat back. I put it back in today and it seems like I have quite a bit more leg room and there still is enough cushion in the back to be comfortable. Here are some pictures.
Here is what it looks like now
Here is the new backing
You can see how much space we saved
Here is what we took out
