Windsheild Wiper Bar?

First let me saythat I had the same problem with the wipers not parking in the same position,I replaced the wiper motor ! Just make sure which motor you have,I purchased a 2 speed,only to figure out that I needed a 3sp/variable one !2 speed is perpendicular to the firewall,3speed is parrallel. About the bushings,I'll save you the leg work,here's where I just got mine !!!
