Ok well done with the bolts, just keep looking you never know stranger things have happened, as to the oil filter spinner, I think that they do one for the FJ model, it's a 1100 or 1200 cc bike but pretty sure the oil filter and spinner are the same? I used one on my FJ and it really made it much easier to fit new ones. Found this on another site
fj1200 oil filter conversion kit. Might not fit but surely worth a look!
