67 rear fuel line bracket finish?

[Mike S]

 I searched the CRG archives (and also did a web search) and can't find the answer.
Is the rear fuel line bracket that bolts to the frame and has a square opening for the end of the line to go through painted or phosphate? I looked at my other survivor but it is lightly oxidized and I can't tell for sure if it's paint or phosphate.
The 1967 AIM P/N is 3912538 as shown on UPC 8/B3 item #9.

Thanks in advance,
Mike

 I'm answering my own questions 

  I removed the survivor clip from the car and examined it under a strong magnifying glass after cleaning it with soap and water and it has a slight gray hue to it (definitely a dried out phosphate look) and I gave it the finger nail test.
Painted surfaces, even slightly oxidized, still feel smooth to the nail but the phosphate surface has more granular feeling to it. Kind of like the feel of dragging your nails across a black board.
I'm going with phosphate finish because I have no doubt that is it.
