Hood latch phosphate color

Re: Hood latch phosphate color

And, based on original cars, I believe that this is not the correct finish.



I believe that the darker version (manganese) is correct and generally deduct under the "Finish" axis if I see coloring this light.

Feel free to disagree with me.

I think the 1968-L1969 were the lighter phosphate and the very late 1969-1976 were the darker.

Different part numbers?

In any event, Alan's car would fit in your later group.

Re: Hood latch phosphate color

The parts were "parkerized"

the color is a dark gray with small glittery metalic in it.
If you put it in the sun, there will be a very subtle sparkle.
The magenese phoshate is correct (like Alan said) and there are kits available on the internet.

You may want to look up Grant Wong on NCRS TDB - he has all kinds of neat phosphating products...

It is a Hot water process - not cold like black phosphating.

Great source for "parkerizing" chems Brownells gunsmith supply.

They are the very best in the business.

I use Brownells for some things, but I believe that there are better sources for Parkerizing solutions. Shooters Solutions is one as is Palmetto Enterprises.

Now you know my other hobby.

Yes, different part numbers and not interchangeable, although very late 1969-76 left side upper can be used on 1968-L69 if the very late 1969-76 lock bolt is also used. I don't recommend it, though.

There may have been different manufacturers of the two series of plates. The 1968-L1969 were manufactured by a firm that used the symbol of an "M" or "W". I don't recall what the very late 1969-76 manufacturer's symbol was. (I have some NOS examples of these but I'm too lazy to dig them out right now).

We should talk.

Re: Hood latch phosphate color

Larry,

Consult with your plater regarding plating the spring(s). Depending on the process he uses there may be some damage to a spring during plating. You might have to remove the spring(s) if your plater recommends doing so. If it were me I would remove them anyway.

[Patrick H.]

Re: Hood latch phosphate color

Parkerizing should not affect a spring's function or strength. Other plating will, of course, affect a spring very differently.

Re: Hood latch phosphate color

Terry,

Thanks for the tip; I'm not contemplating plating anytime soon. I was more interested in a 'for my info' answer, for if/when I do replate.

Most likely, I'd get the kit and supplies to do it myself.

Re: Hood latch phosphate color

This hood latch thing drives me crazy, for the 68. I think I posted this before, but look at the three different versions for a 68. I think they are oldest right to left. Would you have the #'s and info. on them Joe L. The colors look all about the same though. Had to reload cause the file was too large

Which is why I said: ".... depending on the process used." If you are doing it yourself you can contlro the process. If you send them out there is no control.

BTW: When we did Parkerizing in the research institute in the late '60s a bath in heated sulpheric acid was one of the steps. You think that won't damage a spring? I think it would.

Oh yes, that would.
The concentration of acid currently used in the phosphate solutions is very low, and even less once you dilute it 1:9 with water.

We did dilute it with water, but I can no longer remember the concentration. We used fiberglass tanks heated by steam through lead pipes. I can tell you we had the cleanest drain tiles in the city. Nice slope to the concrete floor too. Oh and my sinuses were pretty clear as well. OSHA and the EPA didn't exist back them. We may have been one of the reasons for them.

Re: Hood latch phosphate color

Speaking of hood latch springs, were springs mounted on the rh. and lh. latch. Early 69.
