1962 lancer- inside handle removal?

So I think you can see if you get on the correct side of the clip, push it in with a flat tip screwdriver, and pull out on the handle it will come off. If there is a little rust or they haven't moved since 62, they are going to be a *****! I have a KD steel tool that doesn't work very good, but with that picture you can see where to push the clip in! Good Luck!
