pretty universal. call 'em and double check they will fit on your fj's. i highly recomment perma-cool products.
oil cooler/remote filter: Perma-Cool Engine Oil Coolers - JEGS
i also strongly recommend a tranny cooler for you a/t guys. very simple install, and will extend the life of your tranny.
to figure out the added oil capacity, mock up the hoses and cooler/remote filter to where you want them. cut the hoses. fill up your contraption with water, dump the water out, measure it, and add the capacity of the oil filter you are using. let the hoses/cooler dry completely before you put them on though.
this is what you get (minus the oil/oil filter).
