69 Camaro Speedo Plastic Plug on Firewall
 

Looking to buy an original 69 Camaro Speedo Plastic Plug for the Firewall.

I believe it's 1 inch

Here is what's left of mine.

Looks like the backside says: "Seal 1" Hole / .035 TO .070" and the front of the cap there is a W 24

Found one in the Junkyard today. But still interested in an extra if someone has one exactly like the one described above.

I did get another 6 identical plugs with a different marking, while at the yard today also.
