To get the right angle you will have to take the back plate off the motor and angle the plates in the back to the right number that's on your old one. It will show you how to do it. I have to set mine at 100 from 80.
Also its best to have someone help when doing the wiper angle install so one of you is outside with the wiper and the other is inside. Have fun and take your time. You will need a 6 pack after you are done.
