Problem's when try to mount a Canon FD lens to the camera, after repair

When you have repaired your Canon FD lens, and by accident have turn the lens mount to a wrong position and then try to mount it on the camera or on the back cap, and find out it's not possible, and it's because the 2 red dot's sit 90 degree wrong.

(You maybe already know how to figure it out and know how to fix.)

But if not, in this video I will try to show what's acctually going on and how to possible fix it and put the lens on the camera again , or on the back cap.

Because the 2 red dot's has to sit inline before you can put it on the camera.

it was not possible to set the aperture ring to A when the lens was mount on my Canon AT-1 (it's the only Canon A serie I have at the moment)
