Rat,
I'm sure you saw this thread too. Paul has SO many great threads on here:

He does say "from memory" - and as I just looked up in the rule books, there is no AA/S class listed for 1966.
The breaks were
1964 AA/S 7.00-8.70
1965 AA/S 7.00-8.70
1966 A/S 7.00-8.70
So in 1966, A/S kinda just replaced AA/S. I say Kinda just cuz the 1966 rules were WEIRD - 1 year only. In 1966 A/S you could run any cam and just about any intake, which led to the infamous Jenkins-Stahl duels and that's how the little Nova L79 was able to keep up with the Hemi - cuz it WASNT an L79 any more! A/S for 1966-only was really more like a later Super-Stock class but with Stock tires. This led to 1967 where SS went to multiple classes.

IIRC, AA/S was put in there because, well, it was MOPAR's fault as usual. The Mopar stuff was too light for the big heavy Fords to compete with. Both had good 1963 S/S engines, Ford's 427Lo.Riser and Mopars MaxWedge, but Ford had to put their big fat 63 Galaxie on a super-diet down to 3400 lb to try to compete with those tiny little Mopar cars. That sorta worked for 1963.

But in 1964, Mopar went totally nuclear with - THE HEMI. Ford had the 427Hi.Riser which was maybe 50hp better than their 1963 427Lo.Riser but still not enough in the big 1964 Galaxie - let alone the cost of lightweighting that thing down to 3400 lb. Its not easy to take 700 lb out of a "stock" car! And against the Hemi, even that wouldn't have worked. So again IIRC it was mainly Ford (GM was officially out by then) that pushed for AA/S for the big Galaxie, and let the 3220-lb Thunderbolt take on the Hemi in S/S.

By 1966 all that was kind of a non-issue, Ford had a Factory "production" (if you call 57 cars "production") 427Med.Riser Fairlane vs the specialty-shop 427Hi.Riser Thunderbolt of 1964. The 1966 Galaxie became a luxury barge so its drag racing days were over, and the incentive for AA/S was gone. The 7.00 break now got you into A/S instead of AA/S.

As for SS/A, yes SS/A is in the rule book for 1967-68, its just that apparently NHRA didn't choose to class anybody into it. The Rule Books say
1967 SS/A 0.00-7.00
1968 SS/A 0.00-6.00
NHRA "chose" to run the Hemi Dart in SS/B, by arbitrarily factoring the Race Hemi so its W/P was just over 6.00.
All the stuff I can find says, as noted above, SS/B was the top class USED in 1968-69, so even though the Race Hemi's belonged in SS/A they weren't put there. The Race Hemi Gonkulates at 620hp as run in the 68 Dart/Cuda, which shouldn't surprise anybody since the 427 SOHC Ford was properly rated at 616hp way back in 1964. NHRA "Factoring" was in full play by 1968 and kinda arbitrary.
Davis' book notes this on pg 191, saying the Race-Hemi Dart/Cuda started off in SS/B but blew everything away there so was moved to SS/A, which I think happened in 1970.
