Need help with rpo code D6D

Recently decided to check my service parts id codes in my 86 z28 glovebox and came to a bit of a dead end with the rpo code D6D. I’ve looked in multiple threads and websites to find this codes meaning but have failed. Anyone have an idea what it could mean?

From a list of GM RPO codes, not year-specific, there are these two:

D6D : GEAR, SPEEDO DRIVEN

D6D : COLOR OVERRIDE, TRIM AND PAINT COMPATABILITY
