actually ive already been thinking of the z31 hubs with rear mounted rotor. ill have to pull a set to compare to the ma67 hubs. even then i either have to have new hats made, or get mine redrilled and either put a spacer between the hat and hub, or the caliper bracket and strut. honestly, id rather have a new hat made for this hub setup so i wont have to use any spacers. and since the ms65 hubs are so sought after on toymods, shouldnt be hard to unload them, even at the crazy prices they go for.
