73 Dart wiper pivot arms position.....

Ok so i've finally decided to tackle the dreaded wiper arm bushings. When i bought the car last Sept. only one worked, took the motor off and noticed the bushings were toast. I then took the pivot arms out, problem is i forgot how they go back in??? I have the straight one that has R and L marked on it, and i have the arm that has the curve in it. Help a brother out on this one, what is the correct side or position they go in? pics would be great, i currently have the center bezel and glovebox out to make this easier....thanks
