Anything missing behind the brackets?
I am installing new rear speakers, 1979 and it appears there are the optional brackets in place that are rivetted in place. I have read over and over again the need to get a shallow magnet for this space. Or I have misread this information. When I hold in place a 6 x 9 speaker there appears to be a lot of space with nothing interfering a large magnet. Am I missing something that ought to be there that will interfere that will require this shallow magnet or can I just get whatever 6 x 9 that I like?

with alittle work a 6x9 works fine .its just not the way the factory did it .change to any good aftermarket speaker,will be better than what you had,The front speakers have very little room for the magnets..put your better speakers in the kick panels.

yes the kick panels i have added the speakers and the dash. both were no trouble. the rears look as simple, a 6 x 9 of choice and move on.

There's a mounting bracket that attaches to those riveted flanges with three sheet metal screws, then there's a speaker grillle that the speaker screws to, and then the grille screws to the mounting bracket. So two pairs of parts missing if you want an oem style install. Likely cheaper to just buy a set of the angled aftermarket 6x9 mounts and attach them with a little creative use of sheet metal brackets.

Looks to me like you have stock brackets for the close out panels (L and R) for cars without the optional rear speakers. Factory rear speakers used different hardware.

By the way. Depth isn't the real problem with the factory brackets. It's the diameter of the magnet that causes the fitment problem. While the material quality of OEM radios and loudspeakers of that era was quite good, Delco chose to spec high impedence, low efficiency loudspeakers with low-power, low dynamic range "hard" clipping amplifiers with oversized output transistors and heat sinks. The result was fair sound at low to moderate volume and almost zero chance of component damage if the volume and tone controls were cranked all the way up for long periods even if the horridly ragged sound that ensued was essentially unlistenable.

"hard clipping", "...sink"...?
You seem to know what you are talking about. I'd have to sit down and Google just what it all means, but impressive.
