Engine Tin Air Hose Plug or Grommet?

[N882928]

I have a 2.7L from a 1977 911. The engine tin has 3 large holes. One on each L/R side for the air hoses and another left side aft. Since I will not be installing the air hoses back in the car, does anyone know if someone sells plugs or grommets to close these holes off?

Thanks,

Nate

I have used a 4" round electrical cover plate. About $2. You can use a metal strap on the back side and attach with screw(s) so you don't need to drill your tin. Paint black.
Good luck,
Dave
