Yes, good call from David T. on this.
It's a simple and useful update for Ds built in the initial months. There is a VIN reference for it you will see below. The "top edge" is the rear edge of the panel.
It applies to both of the boards.
To get the stock/untrimmed panels out it helps to push the bulkhead panel rearward at the rear tip of the access panel so it can clear the bulkhead panel when you lift the rear edge up. Remove the access panel and cut the rear edge of it back 25mm. Optionally finish the cut edge by sanding it before putting it back in.
Here is the text from ST-23-1-81. It includes a diagram showing where to cut back the 25mm (1in.) section - if you know which edge is the rear then you don't need to see it. Diagram is not posted here.
CATEGORY: TECHNICAL
ATTENTION: ALL DMC DEALERS/SERVICE MANAGERS
SUBJECT: REAR PARCEL SHELF BOARDS RH AND LH
From V.I.N. 2309, to facilitate removal of the rear parcel shelf
boards, 25mm has been cut from the top edge of both boards.
See the diagram below.
This modification may also be made on earlier vehicles.
