Hey, during the process of painting my engine bay I noticed these 3 holes after removing the fan/heater box. Any ideas?
If there is no pic my photo hosting site didn’t work. It’s the first pic I’ve posted in years after Photobucket changed.

Damn it, only a link 🤷🏽♂️
What are these holes?

Yep, that would be my guess too.
Is there another hole further down, either inside or outside the chassis rail, maybe even in the trans tunnel, for an evaporator drain tube?

It looks like it could be the Mark IV aircon installed at the dealers Ken.

I’ll take a look, I never imagined it had aircon at some stage. I thought the holes were normal but after seeing other cars it seems not.

The air-con fitted in the factory only

The bottom arrow in this pic is pointing to what I believe is the drain tube location for the factory fitted air. (Not the Mark IV)

Do you know if there were two different grommets fitted in the choke cable hole depending on whether or not one was fitted Mick? One with a hole and one without maybe?

On HK-HG if fitted with M21, M22 or V8 M35 they still had the other speedo cable hole so they just put a speedo cable grommet in it, and the cable comes out a second hole (punched later) through another grommet. From memory though the choke hole is just sealed up on WW Stromberg or Quadrajet fitted cars but the hole was smaller than Torana so you’d think they just fitted a normal grommet. It isn’t listed in the parts book but neither is the extra speedo cable hole grommet in HK-HG.

Laurie, no idea if there are different or blank grommets, just know that my factory L32 M20 2/78 hatch had a choke and the cable went through that hole with what looked like a factory grommet..
I just had a look at the front cut i have laying about and it has the hole but no grommet fitted, it was a bare shell when I got it...
