Parchment is a white (or more correctly a white with very light gold tint), your firewall code would be for "parchment" in that case (207 if I remember correctly.) Parchment is what's in my car.
All I found here in a quick look is 212 listed as "dark gold."
You can always ask for a sample of material to check the color against what you have.
Ames seems to be a good place to get interior parts from. Last I knew they selling PUI Interior parts.
