Well, the bushing install went pretty smooth...lubed it up with some White Lithium grease, did not even have to heat it up or anything, slowly it went through onto the linkage arm.
GREAT....right??? LOL
...and you'd be mistaken, just as I was.
Turns out that the 90-deg wiper motor is somewhat re-located in-between the three mounting studs, which mean that the center wiper motor output shaft is no longer where the center of the original motor was...subsequently, I actually can not even hook up the linkage, it is simply too long.
So I'm thinking there are three possible scenarios here:
1) Mopar used a different (shorter) wiper linkage (the part that hooks up to the wiper motor arm and to the wiper pivot points
2) Mopar used a shorter wiper motor arm (I do not think this is the case since the 90-deg motor came with an original arm and the part number was identical to my NOS piece)
3) Mopar used the same wiper motor arm and the same wiper linkage and I simply need to re-index the whole installation on my ride, that would be the preferred possibility since it's easy enough to pop the wiper arms off and re-align things
So before I proceed further, can anyone tell me if I'm on the right path here?
Thanks everyone! (...so close, heck, yeah the install did free up some room, which is what I was after....)
