I checked out the internet for FJ40 engine stuff, the oil pump is vaguely similar, has a bolt down boss instead of a pinch bolt, the distributer drive looks the same,the head gasket appears to have round holes instead of the odd shaped ones on a 235, so the head design must be different, and yes the starter looks very similar.But it seems the Toyota Stovebolt is prone to engine siezures and spun or "burned " bearings, many reports of engine failures.Better stick with the original Stovebolt.
