1969 Hood Striker Assembly Finishes

[cook_dw]

Not a Camaro but a 67 Chevelle I am working on that is a true survivor.  The original owner had painted a few small items on the car under the hood and while removing the black spray bomb I was able to retain the original finishes on the hood striker.  Notice it is natural where the bolts are phosphate.  So I am willing to bet there were multiple suppliers and different standards sent out for said specs.  Before and after photos.

Az car with 12k miles. Norwood built 05A....Joe

What's your take Joe? Its got patina but does the adjuster shaft appear to be phosphated or natural?

Lloyd. I don't have access to the one in the picture as a friend of mine bought the car. The one on my car looks a lot like Hawk's so I took it apart & cleaned the base with a wire wheel on the back side. It has a black color to the metal so I soaked it in carb cleaner. Rinsed it off & same black. I'm thinking phosphate. Paint would've peeled in carb cleaner. The pilot stud I wire wheeled in the thread area. Where the nut & jam nut are, black metal as was the base. All of it looked as hood hinges get after some time & they are phosphate. I haven't done the cup yet....Joe

I did the same with the cup this morning & same thing, it appears to be phosphate also.

The nice thing about cars from Tucson is they don't rust up to nothing so you can still get details even on a car that has 150k miles....Joe

Joe, I will try to check in with you the next time I fly into Tucson to see an old friend that lives down near Sierra Vista.

Here is the exploded parts view that includes the bolt with part number listed.

Please do. I'm retired these days & would love to visit....Joe

I just walked out and looked closely at mine and gave it a quick wipe down. In my 69's case it's black phosphate without question.

While these are nos parts from my collection and may differ from born with, I will let the viewer come to any conclusions that these may or may not offer.

The catch (pn # 3891606) looks like zinc phosphate and the adjuster shaft (pn#3857883) looks like same finish.
The catch is 67 standard by the way.

I believe the adjuster shaft is same for 67-69 but could be mistaken.

Here is the one on Warren's car.

Looks natural or very light phosphate to me.  The cup is heeeeavy phosphate.

Good photo Jon, I’d say it looks natural steel.
Interesting

I's say phosphate and the reasoning is look at the portion of the shaft that tapers to the threads and is out of the way of the spring cup. It has a gray hue to it. The thicker portion you can see where the spring cup has created wear marks.

I totally agree, it’s the same as mine as I posted earlier in this thread. I’ll try to post a picture tonite of mine.

Once again here is a nos plate assembly purchased from a SYC member. Looks to be an early PN# 3891682
I am unsure what this finish is called it is a light grey almost bare steel looking.

that part seems to have an almost 'galvanized' finish, hogdaddy..

The early posted images appeared to be phosphated to me, and the phosphating can be varying shades depending on several variables, and of course it 'ages' depending on the conditions it's exposed to over the past 50 yrs...

[HOGDADDY]

Yes the more I look at it the more it looks to be galvanized. If that's the case I would assume it was done prior to stamping? There are not a lot of galvanized parts on Camaro's.
The only thing that comes to mind are the taillight inner brackets, rocker panel wiring covers and gas tanks.
