Re-installing my rear side interior panels in my 56 (2 door). Doesn't seem to be holes in the body for the screws in the panels. Are there some kind of clips to screw into?? Also..confused about the panel that goes between the rear seat and the trunk. Does it install on the trunk side or interior side??? I guess this stuff should be simple but I am finding these details to be tough. We will now see how I do with the new carpet!
