Plugs in 69t floor pan

Hello,

Got an early 69t, stripping original sound Deadening and came across two white plugs either side near black seat rail?

What are they for?

Here’s another

Could be Ziebart rust proofing plugs from back in the day. They would drill holes and spray rust prohibitor inside the holes.

Ziebart plugs were yellow with "Ziebart" moulded on their centers. Those are factory, and I'm guessing your car is Karmann built.

Hello Mark,

No the car is not karmann but very early 69t Reuter’s. Had all the original horse hair and sound deadening.
Yes plugs look original, need to check but something written on them?

Thanks Lee

I also had these (exactly like your photos) on my early (October 69) 1970 MY 911-S...no idea of their purpose

Hey thank you.

Found some other holes welded up on both sides of car but surely can’t be rush or rot as there in exactly the same place either side. Near to where the plugs are fitted?
They are just to the rear of where the black seat rail fits on the inner sill?

I haven’t a clue why they are there, about 1-1/2 inch diameter, black markers are the holes
