Backwards compatable? Swing arms....

[Persistant]

OK, maybe a odd question but...I have a 93 FJ1200, bought a used Olins shock for said FJ....didn't check carefully enough,,,had it rebuilt with new spring....finally got around to installing and a huge error...     It only fits the previous swingarm configuration.  QUESTION: Can I install the earlier swing arm configuration on my 93 so I can use the rebuilt shock or am I going to have to eat this mistake?
