Interesting your firewall clips to hold the wiring harness are black. I had faded white clips on my 65 and faded blue clips on a 65 4 door sedan I parted out. Interesting that my wagon and the blue 4 door were/are CA assembled
It's only black on the clips holding the wiring and vacuum hoses on the passenger side. The orher ones are painted body color in this case. As you can see there is a gap in the painting due to the clips.
