Two weeks later and my body is recovering from lifting and moving the chassis from under the car body. During the lift process, I found lots of rust in the rockers and sills to finally realize why the doors weren't closing properly. For an instant during the lift I had really nicely latching doors, so there is hope.
I searched everywhere for specific anchor bolt locations. The four on each side were easy to locate. There was mention of an odd one penetrating the spare tire well. In addition there are two at the rear of the trunk going into the rear frame rail, then two at the radiator support. Some of mine were hidden by rust and had no ressemlance to hex head bolts. Surprisingly, most of my bolts came out easily which made it a success. Only one bolt head to chop off.
I drug out a body dolly I have used multiple times and will now refit it to work on the Plymouth body.
