My memory says 66 thru ???? ( Whenever they laid it to rest and replaced it with the 8 1/4,)

Shoot, a member has one available on a 65 he’s parting out.
There wasn't too many 65's with 8 3/4 but it should bolt in. The 65 transmissions had the ball and trunnion front u joint but no issues with the rear one.
Go look at it and take measurements

That’s the plan. Thanks for the info fellas!

Push the button, Max...
Make sure you grab the shock plates and U bolts too.
An A-body 8 3/4 will bolt into any A body from 1963 through 1972. In fact, it will bolt into later A bodies, too, but will have a small bolt pattern vs. the 73-later large bolt pattern. (And I believe an A-body 8 3/4 would also fit pre-63 A bodies, but haven't tried that combination.)
Rear springs are interchangeable 1963 through the end in 1976. (They also fit 1962 Dodge and Plymouth B bodies, whose springs have the same 20-inch front segment.)
If you now have a 7 1/4 rear, the original driveshaft will have to be shortened. Or you can use the driveshaft that goes with the 8 3/4 so long as the donor 8 3/4 is from a Dart and the donor's transmission is the same. A 727 is longer than a 904, and so would use a shorter driveshaft. If memory serves, the 3 and 4 speed manuals are the same length as a 904, but most 4 speeds have a larger main shaft than 3 speed manuals or 904s, so the front yoke would not be the same.
I have the rear end and driveshaft from a 71 Duster 340 in my 65 Barracuda. Because the Duster had a 3-speed manual vs. the Barracuda's 4-speed from a 69 Dart, I did have to change the front yoke. The driveshaft fit perfectly, though. Early Barracuda/Valiant A bodies had a shorter wheelbase than later ones (106 vs 108), but the engine/trans sat in the same place relative to the rear end. A Dart, of course, has a longer wheelbase than the Valiant/Barracuda, so the Valiant/Barracuda's driveshafts would not fit in a Dart and vice versa. (The exceptions being the Dart-based Valiant Scamps, which had the 111 inch Dart wheelbase, and the Duster-based Dodge Demons and Dart Sports, which had the 67-later Plymouth A body 108 inch wheelbase.)
Also: what Professor Fate says. Shock plates for a 7 1/4 won't fit an 8 3/4, and the 8 3/4 also has larger axle tubes than a 7 1/4, so the U bolts are different, too.
