Wierd part needed!

Hello folks! I have a 75 Duster 360. I am looking for a small but important part of the wiper mechanism - under the dash. Attached to the wiper motor is a small bracket which attaches to a metal lever arm about 20 inches long. At each end of this 20 inch arm is a hole which holds a plastic gromment which accepts the tit from the bracket on the wiper motor on one end and the remaining wiper arm assembly on the other end. It is these plastic grommets (probably not the right word) that I am looking for and have no idea where to find them. The number on one of them is 32188 - 103. Any help is greatly appreciated even though I don't drive in the rain, in Florida, you never can tell! Thanks, drmmrboy.
