Engine compartment - Please confirm black or cast colors
« on: May 25, 2017, 12:49:48 PM »
Hello, I am in process of a restoring the engine compartment of my 1969 Mach 1 Q Code 428CJ/C6 car. In my research I have not been able to 100% confirm the colors of some of the below bolts/parts. I am going for accurate to the casual observer but not concours perfect.

My assumption is that all the bolts/parts should be "cast" in color and not black. My car was built in Dearborn in Feb 69 if that matters.

Thank you for the help.


   Four firewall mounting bolts for export brace
   Three studs and nuts on shock tower side of export brace
   Front shock tops
   Hood hinges and springs
   Hood latch and  bolts
   Four bolts above hood latch
   Top of fender bolts
   Ground screws near wiper harness grommet

I am more familiar with San Jose cars but I don't think these details varied between plants so I'll give it a shot.

   Four firewall mounting bolts for export brace
zinc dichromate (gold)....and I am assuming you mean the two braces to the cowl, which I don't think would be considered "export" braces?
   Three studs and nuts on shock tower side of export brace
phosphate and oil, so a grayish flat black
   Front shock tops
on a Dearborn (this one is plant specific) car, phosphate and oil
   Hood hinges and springs
phosphate and oil on the hinges with the springs likely a different (darker?) color since I think they were just tempered/oiled.
   Hood latch and  bolts
P&O on the latch and I am going to say zinc on the bolts (silver)
   Four bolts above hood latch
Two inner ones are P&O and the two outer ones are zinc, though this one is controversial and someone will disagree with me here.
   Top of fender bolts
zinc
   Ground screws near wiper harness grommet
Hmm, on shaky ground here without checking, but if you mean a fairly large sheet metal screw I believe it is P&O
Edit:  large screw zinc dichromate small screw zinc
Some of these that I noted as zinc might actually be cad plated but for your purposes all you need to know is they are silver.

You should invest in the assembly manuals.  They are a great guide to the finishes on most of the components and fasteners.

Here's another great resource. I have not looked at the 69-70 version, but the 67-68 has been a huge help.
