gktech bushings work, but only for s14 subframe
you could probably just drill a new hole to line up with the z33 diff cover?
but i'd want the whole subframe out of the car to have enough room to drill and shit
also, z1 diff cover is super cheap and super good upgrade

AND, apparently people have issues cracking z33 diff covers since they only have one mount point, so this is a good bit of kit to have as well but you could just make your own if you can weld
