dash frame stamp

[northstart]

I started to clean and wire wheel 70 Challenger dash frame and found this cool stamp. Frame is very likely original. Torx bit is 'scale bar.' Does anyone know what it is for?

Where is it on the frame? I have several frames out right now.

It is above steering column, on the inside of the frame (image not from my frame)

Probably not a stamp but a tool mark that's left when they where forming it in a die/jig to hold/lift it.

Yep, you're probably right. The mark does not seem to contain any info. Found another one on the cowl side panel close to where door hinges bolt to, LH side. It's a bit different.
Would be interesting to know which kind of tool was used and in what part of the manufacturing proxess. Love to play arceologist with these cars

Looks like the scar left form the Smallpox shot I got as a kid back in the 60's.

Haha, well it is good to know that the car has been vaccinated but against what? Rust, fuel economy, ricers..?

The marks you are seeing are from clamps. Here is a video of how it is done today. The clamps are different and robots are doing the welding. It will give you an idea of what was done in the past and why it has the marks.

Smallpox or Polio. Can't remember which for sure. Was a while ago.

Thanks! If the production lane was fully automated, the clamp marks should be at the same locations in all cars. If the clamps were positioned by a person, the locations can be at least slightly different.
Have you guys seen these in your cars and where?

Maybe a 1970 thing? I checked 4 frames and none of them have that stamp anywhere. I know one frame is from a 73 but don't know about the other ones.

Thanks for checking!
My car was assembled in Los Angeles plant on 20th of Aug 1969.
I would be intrested to know if all 1970 cars have them, or if 1970 L.A. cars have em, or was it only '70 early cars' thingy.

I have seen the same thing on my E-body muffler heat shields

Cool, which year and production plant your car is from?
I found two more in brake pedal

I bought them at Carlisle, trying to find decent original ones, I don’t like the repops, no idea of the date or assembly plant. Probably part of the tooling for stamping
