Well, I'm not sure about all the parts, but I'll try to tell you what I
know should work and what I worry won't.
Control arms are the same, and I think the subframe is and sway bar
might be, too. Sway bar might be heavier.
The earlier 80Q's used what appear to be the same strut housings, but I
don't know if the hub is the same - ie, if the splines are the same on
the CV joint. Later 80/90Q's use a hub bolt instead of a hub nut, so
they are quite different.

I think the best thing would be to spend some time with the family album
(and test fitting/measuring what you can) to see what is the same.
Even if the axles won't work, you may be able to use that outer cv joint
if you're lucky.
