The B4 rear is similar if not the same as the rear of the B5 A4 chassis so AFAIK it's not interchangeable with a B3 CQ. 
R&r on a bushing isn't that hard really. Can be done without a press using a drill and a hacksaw and a BIG vise to push the bushing in.  Done it more than once.

So I got my '95 90 Quattro onto my trailer to strip it for parts for
my eS2 mods to my '90 Coupe Quattro.  I'm focusing on the suspension
because I have a rear control arm bushing blown out on my CQ, and I
want to use the B4 lower strut housings with the KW coilovers I have,
which have 14mm holes vs. the 12mm in my CQ lower strut housings.

I was thinking I would be able to use the rear control arm off the B4
90Q, but I see that it is different than the CQ rear control arm,
which itself is basically a Type 85 front control arm backwards.  Does
anyone know if the B4 rear control arms are interchangeable with the

If not, then I'll have to replace the bushings in one of my loose Type
85 control arms.  I was hoping more for a bolt in swap for now, rather
than having to mess with pressing out and in the bushing, which I
would be doing with a homemade rig as describe on Huw Powell's page,
http://www.humanspeakers.com/audi/bushings-pix2.htm, which takes a bit
of elbow grease and patience.
