Windsheild Wiper Bar?

LOL The wipers were working. Just as you went messin around under there you bumped the transmission arm off the pitman arm. Oddly enough that will stay together and wear metal to metal for a very long time if not disturbed. The lost motion from the missing bushing causes the incorrect park position.
Lets hope it hasn't worn the hole in the transmission arm to the point that a new bushing wont stay in place. Good luck
