Convertible top latch replacement

How do i remove the pivot pin of a 69 mustang, same as a cougar, convertible top latch?
I have already removed the Phillips head screw that holds the latch to the top frame.

Any success on this? I’ll be taking mine off in about a month to rebush or replace and I was hoping to find some hints before I started.

I’ve never done this, but here is what the Ford Shop Manual for 1969 says to do.
Sound pretty straight forward
