I've read people are replacing rear wiper with Edge wiper.
Now I don't know what I need to perform this little mod.
Here is the picture and parts that make up Edge rear wiper assembly:
1) Wiper arm 2) Wiper arm Nut 3) Wiper arm Cap
4) Wiper arm Seal 5) Blade assy 6) Wiper motor
7) Wiper motor Screw 8) Washer hose Front
9) Center #1
10) Center #2 11) Washer hose Rear
Do I need #2,3,4,5,1. Or just 5 and 1?
