Door handle help

Help
I tried to remove my rear outside door handle on my 52 Buick 4 door
and after removing the assembly on the inside of the door I gave up
now, the outside handle does not work at all there is a bind in the button area. Do I have to remove the handle and then attach the inside assembly??
The problem is that the large clip the holds the handle on will not move, that is why I gave up

Help

Shoot the clip with PB Blaster and pry it any way you can. It will come off.

PB Blaster and a hammer, worked just great.
The handle had to be removed to align the inner assembly. There was a small pin on the handle that is a 100 in a million to do in reverse order.
Thanks
