Yeah, you need to remove the chrome crank and door handle. Everything else is Phillips screws and (gentle) prying.
On a '66, the handle gets in it's own way of using a domestic door handle removal tool. You'll need the hook style.
There is a clip, shaped like omega (omega-clip), between the black plastic ring and the chrome. Force the ring toward the vinyl panel and look down in there. This will need to be pried out.
I prefer the original tool for this job with '65-on Amazon's.
