Hello Eryck,
If you have a 230 before serial 012467 and still have the original two-tone black and white (= light grey) square weave carpet with rubber mats in the footwell areas, just forget it! This carpet is nowhere available in the world (sick!) It was replaced in August 1965 when the new W108 sedan was introduced with the all-black or charcoal-colored square weave carpet. That latter material is still available today in different qualities. GAHH in North Hollywood, CA or other well-known companies can deliver that to you.
Better give your ole carpet to me for a few bucks and go and get a new one...
.
Just kidding, don't worry.
Do you have a pic, then we can confirm.
All the best,
Achim
1964 230 - same carpet as yours
