Parellelling on 3200 MCD

I am currently trying to parallel my blanket cylinder to my master cylinder but I'm not sure what's what in my book pic is bad. It tells me to take out a pin on the lower arm of the master cylinder but I can't tell how the pin is to be removed any help would be appreciated thanks

 

I got it evened out just took some brain storming on my part. I am starting a press repair business so I better start remembering things haha
