This item is great if you want to have the original style ribs in your floor. Not really important unless you're building a show car. I used mine to cut patches to fit the holes in my pan, and it worked fabulously.

I'm new at welding, so this is the great experiment! I had surface rust on my 1970 mustang floor panel on the passenger side, so I measured the passenger side, to find exactly where the pattern in my driver's side patch panel needed to be! I removed the complete driver's side front factory panel up to the seat platform front, which left a quarter inch area across the front of the seat platform for this patch panel to sit level.. I removed the floor clear up to where it lays on top of the toe panel. I had damage clear up tp the beginning of the transmission tunnel curve, so I needed an extra piece of 18 gauge sheet metal to fill that area. The piece I removed from this new patch panel was the right size and length, after using my body hammer to straighten a small pattern that was left in the piece. Once I had my patch panel cut to fit, I drew lines across it to match the mustangs bracing pattern, so I knew where to drill my holes that I would rosette weld. My welding job wasn't the most beautiful I've ever seen, and I did spend way too much time grinding the welds, because of my lack of welding experience! Anyway. This patch panel gets two thumbs up, because I only have two hands! If I had three Hands it would get three thumbs up! Definitely saved the day on an otherwise beautiful, all original California Car! You can't see any welds from the bottom of the car, it looks perfectly original and untouched! If you need an original pattern patch panel for your 1969-70 mustang or cougar, you found one!

I wish I could add pictures, so you can see how well this worked out for me!
