Projects 1949-51 Mercury Rear Quater panels removal?

I wounder if you know how to remove the rear quarter lower panels?
Do you do it from the inside of the car?
I see there is 3 screws in the door jam and some under the rocket panel
but what holds them in place in the middle of the car
and how many bolts are there?
Does anyone have any pictures on how it looks inside when it is removed
It's my next project and want to know how big of a deal it is ....
thx

Don’t know how many but inside the trunk you’ll find the bolts attaching the lower qtr to the upper qtr

 

You also have to pull out the back seat and the side panel/armrest. I replaced one on my 51 back in the early 80's and it was more tedious than hard.
