Bring my 73 dart swinger back to life.

Trouble with wiper drive arm. First photo drivers side wiper in park. Second photo passenger side in park. Third photo of motor w/drive arm going to motor. Next 2 photo's are of my drive arm. Center line to center line. For a total of 22-3/4". Last photo is of my drive arm connected to the to the drivers side wiper in park. It's 2" to long. I wish i had that problem and not my wiper drive arm. What do you think if I cut it to fit and weld it back together.:coffee2: If someone has a 73 Dart with there dash apart could you measure your wiper drive are for me.:coffee2:
