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.
> Also conversion of front 4x100 to 4x108 would go along with
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.
