Title: Engine compartment - Please confirm black or cast colors
Post by: jgkurz 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.

I edited my reply regarding the wiper harness ground screws.
