64 and 65 are the same. 66 is a big change to the strato bucket but has no back locks. 67 is the same as 66 but HAS back locks. 68 and later are wider the the 66 to 67. Don't ask how I found that one out.

Just want to make a correction... 66-72 buckets have the same basic overall dimensions. 68+ is not wider.
Springs, buns & covers can all interchange between 66-72.
Yes, there are subtle differences between years and models, the seatback locking mechanisms, headrest style and mounting, even some unique upper cushion spring assemblies for certain years/models, definitely tracks can be unique between body styles- but overall dimensions are the same.
64 and 65 have their own unique issues... A-Body 64-65 seats do use the same frames, however the lower spring assemblies are different depending what the original car was. Chevelle Lower cushions have rounded front corners where as Buick/Olds/Pontiac had "Pointed" front corners of the lower springs. Luckily it seems (in my experience) there are way more of the BOP 64-65 buckets than the Chevy versions... But be aware, if you tried to put BOP covers on a chevy lower spring assembly it would not fit right.
64-65 "Chevy" Style lower cushion spring assembly- Note the front corners
64-65 B-O-P lower spring assembly, Note the front corners.
To make it more complex, the 64-65 a-body seats LOOK like the seats used in 62-65 Chevy II, F85, Corvair and a few others, however they are NOT THE SAME. Those are actually wider than the A-Body seats, so covers and buns and stuff won't interchange.
There are a LOT of those seats for sale listed as a-body seats, don't be fooled. The way you tell is to count the main springs visible on the underside of the lower cushion.
True A-Body 64-65 seats will have 4 main springs. ChevyII,F85,Corvair seats have 5 Springs across the bottom. B-Body (fill size) buckets from that era also look similar but are even wider still, those also have 5 springs across the center.
True 64-65 A-Body Seat, 4 main springs visible on the bottom (can count the retainer tabs at the front of the frame to be sure)
62-65 ChevyII,Corvair,F85,Skylark, etc seat: 5 Main springs visible across the bottom:
Actually remembered yet another random detail someone sent me... 65 corvair seats actually ARE the same as a-body (4 main springs) but the earlier ones are the wider ones.
So all that to day, if you are buying 64-65 seat cores to restore- count the springs!!!
Anyway, hope this info helps!

Well, no- Those pics and details are related to 64-65 seats
66-67 seats have their own unique details, but here are the primary ways to identify what you are looking at:
66/67 "should" have metal sides and back panels with imitation vinyl grain stamped into them
66 will have no seatback lock, it just flops forward.
67 & 68 have a seatback lock with a chrome release button on the outside edge of the upper seatback
68 Has plastic sides and backs, headrests are extremely rare as it was optional
69-72 has a seatback lock with a large plastic chrome release button in the center of the upper seatback. These all came with headrests.
basically any 66-72 seat can be turned into a 66 seat by removing the seat back lock mechanism and putting a 66 back panel on it (without an opening for the release button) and removing the headrest components.
67-68 are harder to find, 69-72 are the most common.
I'll bet you you can not hang a 68 seat back on a 67. That's why they are listed differently.
You absolutely can, just need to fab the 68 style back panel hooks. They both screw onto the back of the frame, you just need to know or work out the mounting location.
Same thing the other way around if you want to put 66/67 backs on to 69-72 frames, you just need the 66/67 style hooks.

Thanks for your detailed review. Like what was stated. If you look at the chevelle seats. They look more fuller or boxy.
maybe that was throwing me. Then , it was posted that 68 seats don't fit 67 frames . Overall thanks for the information
Okay. For someone who doesn't have a dozen pairs of buckets the correct information is that seats don't fit other years unless you have multiple different year seats to manipulate something that is incorrect. The correct information is what people need.

well 66. Sir. I don't have multiple seat.
I just questioned. Because they looked different. No biggie, I believe we can all agree that the 65 seat can't inchange with 68 parts. But the information provided. Which I can't question. But i can use as a reference.
