There is some misinformation above... some parts will bolt in place of others, but they do not swap directly.
The upper rear control arms are DIFFERENT GEOMETRICALLY between a c5 and c6... the ball joint hole is further back on one of them. (The C6 I believe.)
The rear cradles are DIFFERENT due to the transmission mount and springs.
Z06 Upper rear control arms are a special breed as well.
The C6/C5 rear LCAs as the same geometrically, however NOT interchangeable due to spring mount differences. (unless you use coilovers... then they are a direct swap.)

On the fronts, I believe the steering rack mounts a bit differently relative to the lower control arms resulting in different bump steer characteristics... but I cannot personally confirm that.
