CGT axle questions

Major: Will axles and/or cv joints from earlier years
       swap onto my 87.5?  A RF outer joint ball cage
       is destroyed.
       After the outer joint came apart in the last turn
       into the driveway, the inner joint may have
       suffered from the thrashing --at least the boot
       is ripped to shreds.

       I'd rather get a complete original axle from the
       yard than any other option, but the '87.5's are
       not common here, any experience on what swaps?

Minor: Is it true that right and left axles can be swapped
       to good advantage?  The theory I've heard is that
       since they are equal length they can and that used
       OEM will then wear better.  Are they really
       "bi-directional?"

       On other cars I have not had good luck with rebuilt
       axles --and on other cars I have never considered
       going for 300,000+ miles either.
