Rob,
To convert a Condex to left hand, one needs to remove the spring and reshape it to accommodate your intentions. Although the Condex was the simplest and most affordable reel, it's also the most difficult to reverse and adjust.
On the Pridex and Beaudex you can remove the stanchion to take the spring out, reshape it and put it back in place.
The problem with the Condex is that the stanchion is riveted in place so the spring not only needs to be pushed out but also needs to be pushed back into place - meaning any reshaping of the spring will be altered once you push it back into place. This needs to be anticipated when shaping the spring and that really comes with experience (and on any model, a little bit of bending of the spring goes a long, long way to altering its function).
The Condex still frustrates me to no end - much more difficult than the other models.
If it is a gift and something you really want to keep and fish, I'd suggest you send it to Bulldog to take care of it. He has a lot of experience reversing these reels (and can probably can do it with his eyes closed).
. ..or learn to wind right hand.
