Superbird Negative Battery Cable Ground Wire Screw Question

[Mopar John]

I have another original Superbird question for the guys with survivor cars.
The screw that attaches the negative battery cable ground wire to the core support,
Does it have a screw with a captive washer or a screw with a shoulder around the head.
While we are at it what logo if any is on the head?
I have attached a picture of the screw in question.
Thanks! MJ

While your at it can you look at the air cleaner instruction decal on the air cleaner lid?
I would like to know if yours has " severe conditions " or just " conditions " on the bottom line?

This is how mine was/is when I bought from original owner,stud with nut.

On my green barn find, which was a 1-owner not touched since 1974, it was a one-piece bolt and washer that looks just like your first picture. On my white bird which was never touched since new before I got it, same thing. On the green one I can't see any markings on the bolt head-too rusty, and on the white one I am out of town and don't have a picture of the front of the bolt. If it is important I can get it next week. I also looked on my blue one, but no pictures, and on the purple Bird race car it was missing.

Bob,
Thanks for taking the time to investigate and reply.
The screw with a captive washer in my original picture is actually 2 pieces.
That is why I posted to see if the correct screw is a 1 piece with a shoulder?
You can hardly tell without loosening it up.

I'll reach out to my friend Dave with a Survivor Bird tomorrow...

Hi John - Sorry, I didn't see your post before I took pics. I'll check the decal tonight.
Here is mine - it has a bolt and nut. I'm wondering if it was a running change in production or possibly what they did if the weld nut wasn't on?
I need to remove the nut and see if there is a weld nut in there. Looks like we have them both ways so far....

[Mopar John]

Jim,
Thanks for checking and the picture!
It looks by the lack of orange paint in a rectangle that the weld nut came loose.
After that someone may have gone to the setup now on the car.
In the reply from 62 Max the weld nut is still there with a similar setup.
So this item like most has become more complicated and we need more examples!

On another note,what is the significance  of the arrow stamped in the core support next to the bolt/stud ?

Maybe something in the original core support stamping process?
Is there something on the other side that lines up with the arrow?

More information on my original question.
I have removed the 2 piece screw with captive washer from my original picture.
It is the one on the left and you can see when loosened up the 2 pieces.
It's hard to tell it's 2 pieces when it's installed.
In the picture on the right is a 1 piece screw with shoulder that looks similar to the 2 piece when installed.
Now just to find out what was there when built?

Here are some pics of the one on my bird.

Im gonna go out on a limb and bet this one is not OEM

Don't know if this helps but here is a pic of an air cleaner lid I just restored. It is from a complete date code matching 6 pack set up. The date code on  a couple of the carbs is 3209. The only thing is it was on a dodge not a plymouth. Larger decal was Six Pack. This air cleaner also has the metal flange in the front. Non Air Grabber type.

Here are some pics of the one on my bird.

I think the OP is going to struggle to find another 6 foot long screw!

[Dragon Slayer]

One that came off is a self starting sheet metal screw.  It would be used in an unthreaded hole.  Example, vacuum canister held to frame with a screw like that. B body brake distribution Tee also use it.  The one on the right would be something used in a threaded type nut.  Similar to the one shown in reverse on your original picture.

Now, why a stud on a welded nut?

The one on my Hemi 'bird is the same as chaaargerb.  I have 3 extras if anyone needs one. WINGNUT

E-Bodies use that screw as well....should be silver zinc plated

Hi John - here is mine. A lot worn but I think it will help.

Yes Jim, it will help!
That is another example of the Superbird six barrel lid with just "conditions" on the last line of print!
I sent a pm to chaaargerb because I couldn't make out his in the reply.
The answer I got back was that original decal was also "conditions" only on the last line of print.
Thanks to all! MJ

                                     Back to the Superbird Negative Battery Ground Cable Wire Screw!
I had been thinking about this quite a bit and then I remembered that I had some core supports I had cut off cars.
So down to my basement I went to look at what I had.
My first picture shows the core supports.
I was hoping that I had a 1970 core support with the Negative Battery Ground Cable wire screw still attached?
Well, I was losing hope as none of them had one attached!
Then I got to the last one marked 1970 and the screw was still there! WOW!
It was there but rusty as shown in my second picture.
I removed it and I couldn't make out any markings stamped into the head.
Then I took it out to my shop and measured it and it was the same size as the one chaaargerb has!
I will share with you what happened next in my next reply!

                                                     Superbird Negative Battery Cable Ground Cable Screw Part 2!
So the next thing I did was get my engine compartment hardware drawer out again and dump it out on my bench.
That is my first picture.
With the knowledge I got here and a sample I started sorting through the hardware looking for the correct screw.
About two thirds of the way through I found one! It even has the correct logo!
I show it in my second picture.
I cleaned it up and installed it on the Superbird.
I show it in my last picture!
Thanks again for all the replies, pictures and help!

Man I've got some real head scratching going on now... I know my vacuuum lines/wire harness is run wrong through here (and not over the support), but I don't even have the welded in nutzert.. or a hole for same!

[held1823]

i recognize that basement parts stash, and may or may not have lightened the core support supply by one
