I just installed that cheap knockoff floor bar for sale on ebay. It's thicker and heavier than I thought, probably 1.5" thick. It looks like it was hand made by someone but it seems really strong. It was painted a silver colour which didn't look too great plus it got chipped during shipping so I painted mine flat black. Installation was fine but I had to drill and tap another hole in the frame to install 2 bolts per side. The unit looks like a universal item for many cars. I think it would have moved around with only one bolt. I did noticed an improvement with the top off, feels more solid and stable with less of the wiggle/vibration. It didn't completely get rid of the wiggle but it did lessen it. It's a good deal at $80 for us guys who can make it work.
