Floor pins - retaining insulation/carpet

[zambo]

Stripping the tar boards off the front interior floors, I came  across these pins. (This one just happens to be on the tunnel). 
 

It seemed like they were to keep the fibre board insulation in place. Were these on all cars?
 

I’ll be hitting them with a dremel so I don’t catch my fingers again and due to the fact the replacement stuff is self adhesive. 
 

Were they “shot” into the floor at interior assembly stage?

Yes all 02 I've seen have the pins and they were installed before paint, and yes they are good at puncturing skin🥺.

I had rust repair work to do to the front of my pans, so I cut off what was left of those pins and then welded on homemade tabs to replace the rusty pins on the floor.  I'm a fan of the original fiber board/tar/foam sound proofing.  The self adhesive stuff is vibration dampening, whereas the fiber board pieces absorb/block sound.

 

 

 

 

I gave mine a coat of varnish the last time they were out of the car.

Wow!!  I was about to write in about these strange pins I found sticking out of my floor after I stripped the interior.  Looks like they were there from the beginning.

Weird, don’t have those in my very clean ‘74, nor any apparent missing pins.

Thanks Tom - I didn’t mangle the fibre board on the way out so still useable. And the varnish idea is smart for longevity - and they do provided good sound proofing.

Yup, they are in my 76. Or at least the ones that didn’t fall out with the chunks of missing floor. I’m about to cut out the rest.

Mine is a 1975, October build date.
