the toyota ifs is pass drop if that helps(r180/200 hitachi), axle shafts are pretty easy to come by with a bit of either work or cash earned with work. .. or any other way for that matter. spindles........... maybe the front spindles from a dana 30 or similiar? mount the a arms to the existing ball joints, both of which point up iirc (i don't much d30/35 stuff, 44/60 ball joints point up), front steer so thats pretty easy. a bit on the heavy side but do-able i should think. i'm sure toyota made an awd sportscar but can't remember the name. nissan has the skyline and they have an ifs 4x4 truck(r180/200 hitachi on the truck, drivers side drop on the truck when i had one, pass drop on the skyline) but i disremember what the spindles look like. dodge dakota is ifs/torsion bar/unequal control arms with a 7.25"(?) diff and cv joints on the outside, still front steer. theres probably a dozen more but those are the only ones i've worked with to any extent.
storage jar must be getting full, all the new info keeps spilling out
