Some more information but I am not sure it will answer anything. In 1973, I ordered some carpet pieces for my 1966 230SL 4 speed, blue interior, from the local Mercedes dealer. I have no idea why I ordered them since now, over 40 years later, the carpet in my car still looks decent. Instead of sending me the square weave like I had in the car, they sent me loop carpet like was in later 113s. To tell the truth, the pieces of carpet look pretty shoddy compared to the square weave carpets that came with the car. When I objected to what they had sent, I received a letter saying pretty much that I should feel lucky that I could get any kind of parts from them for older cars. I never installed this carpet and I still have them. They still have the MB tags with part numbers, dates, etc.
On the carpet for the tunnel, there is a vinyl binding around the hole for the shifter as shown in the picture.
If anyone can use these pieces of carpet, they are free to anyone that will pay for shipping. I have 3 pieces (I thought I had more but do not see them now). I am not sure where the other 2 go.
