Adam, those wheels in your link are the common wagon wheels seen on earlier cruisers. They aren't factory, but they were a common dealer add-on back in the day, so they're almost more common than the factory wheels.
The factory wheels for your late model FJ40 can be seen in these pictures:
I believe they are the same as the FJ60 wheels, only painted white. Though some FJ40s did come with these wheels in factory chrome.
