[Healeys] OD condition check?

[ggilliam at usol.com]

Hey List,
  I would like to know if there is a way to test the static condition of 
a trans/OD while off the car.
  I have a "spare" centershift/OD I hope to install in place of my 
sideshift, no OD with clanking 1st gear and bad synchro. It would 
be beneficial to test, etc. before installing.
  I have a centershift tunnel, but what other difficulties will I 
encounter with the replacement?
 Thanks to all,
  Gordy
