That sure looks like a Toyota non-USA floater. I had one from an Aussie FJ60 Land Cruiser in my FJ40 LC but those were 6 lug (offset differential.) All of the Toyota trucks/LC's and other variations are offered with full floaters pretty much everywhere other than North America and the 2wd versions would be 5 lug. From the early 80's to 90 (or so) the 2wd 1 ton was also available in the US as a SRW 5 lug and DRW 6 lug.
