Another "Identify this c-body part please...."

[Captainfury]

Hi All,
I'm still repairing/restoring/cleaning 54 years of wear/tear and general lack of love on my 1971 New Yorker 2 door, and recently removed the rear bumper and valance to address the non working lights and build up of gunk.
Looking into the trunk, I noticed that there were 4 "nuts" that appeared to serve no function. Further investigation, and I realised they held down pieces 3446105 and 3446104, on the left and right sides respectively. From the weight and feel, these body pieces would most likely be made of aluminium, which is most unusual.

I have attached photos from my experiences. These pieces attach above the backup lights, laterally to the trunk lid. See attached photos.

What are these pieces called? Why did the attaching "nuts", get filled with a rubber like substance during assembly? Was it to mitigate against the effects, (such as loosening) of repeated trunk opening and closing?
Any information on the name of these 2 body pieces and material of construction would be really useful.
Thank You

Those are quarter extensions. They are used so the same quarter can be used on many trims while changing bumpers and tail lamps. The same basic Chrysler quarters were used whether it was a Newport, New Yorker, 300 or Imperial. They are made of pot metal. The nuts are filled with butyl because it weatherproofs the trunk.

Mastic nuts. Keeps the emblems and extensions tight and from rattling and as said above keeps the nut side dry

Thanks for the quick and very informative reply The_Eagles_Nest. Interchangeable pieces has its benefits, and makes changes to the various cars easier, like you suggest.
I saw another thread referring to pot metal, and I will look into that alloy. Do you know if pot metal is an alloy containing aluminium?

In the LA fires in Altadena last January, there was a photo found of a C-body that burned. These pieces were completely melted away while the steel shell of the body remained...

c body lost to the California fires

I am not sure what pot metal is exactly but I understand it as an amalgam of zinc and low quality garbage metals.

Thanks for the help HWYCRUZR!!
I'm going to order a box to freshen things up.

Those fires were horrific..
I was astounded by the loss of so many homes, and the personal effects within.
We get out of control fires down under, during summer too, however the fact that LA and Australia's eastern seaboard are very different in the density of housing/ development/infrastructure, the fires here never destroy more than a few houses at a time.
On occasion we may get 10-20 houses burnt down, but it's rare.
I saw a video of the LA destruction, and a certain neighbourhood experienced every street completely wiped out, going on and on and on and on........
It was hard to imagine how many people would have lost so many treasured irreplaceable items. I felt really sorry for them.

With all of the wildfires in North America and Canada last year, plus the tornadoes, hurricanes, and floods . . . it kind of makes one think about saving ANYTHING of value anymore. Cars included.

In the case of the LA fires, the houses have to be rebuilt to their original size and such, or the insurance companies will not pay the claim, as I heard on a news report. No "cashing out", it seems. Any upgrades to make the new structure more fire-resistant are on the owners, too. AND rates probably go up, too.

Take care,

Yesterday a local council not far from where I live, proposed an 85% increase in rates for business and home owners within its borders. Not surprisingly, people were shocked and angry. The Council has a record of poor management for many years, and it seems that now they want other people to fix things. Fortunately, the people concerned took the proposal to a higher state body, and it was thrown out!

Have a great day CBODY67
