Mustang Bullitt Pedal Install- Please Help!

Ok...I really need help installing the accelerator pedal.

The instructional video from American Muscle says to remove the 2 bolts and disconnect the accelerator cable from the the top end of the accelerator pedal assembly.

I CANNOT disconnect the accelerator cable from the top of the accelerator pedal assembly. They made it seem so simple in the video..."just pop it off". I've been at it for almost 2 hours. I know i'm a noobie but im trying my best. Does anyone have any ideas? Attached is the video link below. Thanks all!

I see what you are saying...

But even if i pry off the cable first, how would i reattach it afterwards because its held in place by a retainer. The retainer will be ruined/useless once i pry off the cable.

Any ideas?
