I believe that rear axle can be used, from what I have read long ago. 
Also, the 87.5 coupe axle will work (comes with discs, 4 x 108).

I think you need the axle, not just the hub stub things.  Some big 
awkward bolts to undo, but not a big deal, really.  Lets you replace the 
trailing arm & panhard rod bushings.  You'll probably need to use the 
disc brake proportioning valve from the donor axle.

Any 85-87 coupe or 4kq strut housings will have the hub you need.  You 
can swap the entire housing if you want.  I may have a few sets lying 
around if I didn't scrap them...

I believe the '84 already has the larger diameter rotor, and the caliper 
should accomodate the thicker 85-87 rotor with the right pads.  If not, 
get the parts from the same donor vehicle.
