What is it called?

[Projectile Dart]

I was recently trying to service my passenger side window in my 1968 Dodge Dart 2 door sedan (not sure if it matters) and I noticed there was a little plastic pin on the bottom of the glass that secures it to the regulator. As soon as I touched it, it disintegrated and I don't have another one to see what it was supposed to look like (driver side glass is out of the car and needs the same pin on that side)
I've tried Google and the search here and I am not even sure what is it called but can anyone help me find a replacement or if they aren't reproduced then if I could at least find a picture, I can look into making one myself to secure the glass.
Thank you in advance

Maybe? I don't have anything to go off of but based on the glass and the regulator it seems like that might be it
Is there any other styles?
If not then it has to be that

I used a piece of nylon tube or spacer with a bolt through it.

There might be different pins with a different OD.

The Blue ones were off of a 67 Dart / Barracuda

The OD is 0.490

The overall length is 0.570

The OD of the head is 0.750

The thickness of the head is 0.100

The lock pin is 0.700 long

The lock pin OD IS .330 at one end and 0.320 at the other.

Pretty certain DMT carries them, but I forget what they're called. Window regulator fasteners?

They are called a window glass “rivet”
