I think Dave has misunderstood the situation. The wipers are supposed to work in the opposite direction to each other - "clap hands" mode. 
If, as you imply, they are not doing this, the remedy is to loosen the wiper wheelbox that is parking at the wrong side, disconnect the cable (I think you can do this by removing the two nuts on the back, from memory) - probably need to loosen the other box and possibly the connection to the motor. Turn the box upside down, so that the two boxes have the cable at the top on one and the bottom on the other. Reassemble, then adjust the position of the wiper blades as Dave indicates. 
The tubes can be bent, just make sure you don't kink them.
In other words, your suggestion is the way to go.
The single wiper motor may not be a replacement - this was standard from 1967, and even if yours is earlier, the firewall may have been replaced, complete with the wiper setup.
