door handle slop question

[49gmc]

ok, i got the little spring to fix door handle slop on the pre-52 or whatever year it was AD's. i took the window track thing out to make it easier, and i think that i have to take out the piece that elbows inside the door that holds the latch and stuff, but how do i get off the the little pin that goes through the arm that is coming from the inside door handle. sry, i know that is prolly really hard to understand. if anyone can figure out what i am talking about, shoot me answer.
