My car has a roll bar in it from a previous owner. They welded it under where the rear seat would be (behind the driver and passanger) and ran the bars into the trunk but never finished welding it back there. The guy gave me the original interior so I was gonna cut the bar out and put the rear seat back in. I was wondering if the bar is strengthing up the frame any or is it just a "safety" thing. If its nothing Im just gonna flush cut it to the floor, but it it does strengthen any (how it is now) I will leave it stubbed up and weld a flat bar between the two. It will be under the rear seat so you will not see it.
