thanks guys, I couldnt see how it could hurt either. the material i used measures 0.13 inches. We had a bunch of pieces laying around the shop that just happened to fit perfectly between the two sides. i had to narrow it out at the front control arm mounts, but that was easy with the plasma cutter. then i stitch welded the full perimeter of the plate.

I only did it because i had the floor out, and now i have a plate above the front leaf spring mount for a cage... maybe. I was also thinking of making a cross member from leaf mount to leaf mount.
