My car's dash is based on the 65/66 Monaco's so I bought the Custom Autosound 3001-DVC, it says it's a 4x10 unit, however sticking it into the dash speaker spot, it seems like it's too short front to back, almost like the hole was designed for a 5x10 speaker rather than a 4x10 one. Did the factory speaker come with a a surround to fill the gaps or was it just shaped differently? I know I'll need to snip off the tabs at the sides to actually get it in, but otherwise there's no real way to mount it to the dash.

Does the speaker perhaps bolt to the speaker cover? On my 66 Dodge (Canadian built) the speaker bolts to the speaker cover.

Some USA built cars like Chrysler and Dodge used a 6 x 9" speaker with separate adapter tabs at the ends. That may be the case here.

The USA built dash for Dodge has two round gauge pods, and the Canada built dash for Dodge and Plymouth has a square single speedo arrangement, and uses a 4 x 10" different speaker. Which dash do you have?

Also, if your car is a "built for Australia" unit - Dodge Phoenix, they may have used a different arrangement because of the conversion to the dash to RHD. They used a USA built arrangement, but I do not know what size the speaker was.

Definitely not - the outermost holes in the corners are where the cover/grille is screwed down. there's one at each corner, you just can't see the two closest to the windshield from the angle that I took the photo. Seems like the speakers are just held down with two smaller screws.
 
I'm pretty sure that dash uses a 6 x 9 speaker. My '65 Chrysler has adaptors like this, but your dash may be different.

Hmm...I can only assume it's based on a 65 Monaco dash, because the part number of the cover was 2491598 and looking that up took me to listings for 65 Monaco speaker covers. I don't think a 6x9 will fit because the hole is 4 inches front to back, and a 6 inch looks like it wouldn't fit. The 4x10 could actually fall right through the hole if I cut off the side tabs
 
There's an ebay listing for it:

It looks exactly like that. The car didn't come with a speaker at all; the first owner decided not to add a radio in. Had a blanking plate over the holes for the front of the radio.
 
OK. So, you need to find a speaker that has its mounting holes that fit those four holes in the cover.

At this point, it's just a matter of mix and match. The challenge for you of course, is that you're in Australia.

The little I can see of your car's hood from your first picture of the speaker opening does not suggest 65 or 66 Dodge Plymouth or Phoenix to me, but I could be wrong.

Can you post a picture of your entire dash?

Perhaps seeing it will give us some insight into which speaker is the actual fit. Perhaps the factory used some oddball speaker.
 
What you can do is make up an adaptor to fit the speaker to the hole. This is one I made from a piece of 1/4" particle board (actually a left over shelf from a piece of cheap furniture).

I'm not sure that is the case - in my first pic, you can see the holes in those corners are at an angle, to match the cover. I don't know of any speaker frame that would accommodate that. If anything, it seems like those two small holes

That's because while the exterior matched the same year Fury for most of its production, the interior from 65-68 stayed the same 65 Monaco dash, just mirrored as RHD. I wonder if Chrysler ever made RHD Monacos, because they went to the trouble of mirroring the dash, but the wipers are old-school clapper style, rather than a parallel action just mirrored across for RHD. Maybe they decided it wasn't worth making a whole bunch of extra wiper parts for such a small market.

The pic is kind of shitty because it's the dead of night here so I'm just relying on the camera's flash. I measured the edges of the hole and it's exactly 4x10, but that's just the hole, not the surrounding flange.

Also I just realised that you can see the speaker grille where I left it as well lol.
@Big_John I was thinking of doing something like that but with some sheet steel, as the Custom Autosound speaker has its own cover that seems to be about 1/4 inch thick and first impressions are that it would be pressed against the speaker cover. Wonder if that alone would hold it in place if I were to bend the steel flanges on the speaker itself flat...
 
To keep the metal from "rattling", you can get some adhesive rubber flashing at Home Depot (or similar) and put it between the metal-tometal contact areas. As it is usually in a wide role, some trimming would be needed.

In the aftermarket, it is common for the screws which hold the speaker grilles down to also be long enough to position the speaker with on the backside of the metal panel, to which the nuts with locks used to secure everything in place, from the bottom.
 
I've got some felt tape at the ready in case it does rattle. I haven't driven the car very much yet but I figure being a nearly 60 year old car, any other rattling will distract me from the speaker rattling. Lol.
