ISCV are same, the only difference on the tb(afaik) is the 2wd uses a slightly different idle speed screw, that is longer with a locknut, where the 4wd doesn't use a lock nut and has a shorter screw, as I say afaik.

Yes ST TB is different, not to do with the idle screw it's bigger IIRC, also some ISCV'S incorporate a diode (Which is indicated on the top) but esentially it's still the same.
