Just swap the syncro over would be best idea.
If you ever snap a cable again. stop the car to a dead stop, put it in gear, and start it off the starter motor, at least you won't mess up the internals of the box. I've float-shifted my way home before when i snapped a cable, wasn't pretty for a few shifts, but worked well.
Newbie reassurance...so any SR20DE tranny
synchro will interchange to the SR16VE tranny.
