Please do. I think I understand what you are saying. Maybe you have them upside-down or mixed up side to side? You can install them any way you want but usually the angles face forward to tilt the seat back.
I used them on my car. The pic below is from when I mocked things up. I reupholstered the seats after I fit them in the car. The seats are from an old Jeep Scrambler but they are similar to the A100 seats.
