I am trying to convert my non delay on the dash to a delay with stalk, I went to autozone and bought the delay wiper model for my car and it will not fit the motor hits the brake booster?are the motor's different sizes,I thought that it was just the delay module added to the front of the motor? I tried to line them up in different angles and they look the same? just can't get it to bolt up,I threw the original away by accident so I cannot verify with that one at this time any help is appreciated.
