I contacted GAHH, very nice folks. Very helpful.
They don't have the part I am looking for, so I think my only
options are change color or re-dye the 8F32 to 8424.

They sent me some samples of mbtex and velour carpet.
The GAHH carpet colors Beige and Lt Beige are very good matches. The Lt Beige is actually not an 8F32, but I think it is a better looking color. The mbtex and carpet samples are probably superior to the MB oem parts. The only problem is the carpet
is not molded but for straight pieces (rocker panels) it is perfect.
Even footwell pieces could be made with a rubber/foam/silicone material molded to the floorpan. The only tough piece is the back section as it has some pretty complex curves.

At this point, I think I may go with the 8F32 color. It makes the door panels appear more greenish but I think it looks pretty good.
