Need Help Identifying Seats In My '62 Cj5 (correct Vintage?)

As I get deeper into fixing/tweaking this cool little Jeep, I'm realizing that it is somewhat of a Frankenstein. I'm sure I'm not alone.
The good thing is that the non period-correct mods are things that I would have done myself. My hat is off to the PO. I love the Dauntless. The electric rad fan is nice to have as I figure out the 225's temperament on 90°+ days. I'm glad the wheels and tires - pretty much the whole exterior isn't too much of a departure from the original look.
This brings me to the seats. Although I have a new pair of low back Smitty's on standby, I really like the M look of the canvas seats... to the point where I don't want to replace them with vinyl - even if the Smitty's would undoubtedly be more comfortable. The Olive canvas is totally shot however.
As I search for "canvas seat covers" for a '62 CJ5, I'm not coming up with too much. Walck's only shows vinyl covers that cover the seat backs.
So my question is: Were there two styles of seats for '62: canvas over foam with open backs like mine; and vinyl over springs and batting with covered backs? Most images of original CJ5's show vinyl seats - much more contemporary than the basic canvas Army-style seats that are in my CJ.


Here's what I have (please excuse the in-a-pinch Walmart clearance cushions).

 

I thought the driver's side was the 2/3 side, and the smaller 1/3 side flipped forward for toolbox and rear seat access. Those look like M38A1 seats to me.

 

The driver's side straddles the gas tank and bolts down in 4 places. The pass. seat flips forward on a pivot to reveal the storage box. I'm guessing that's the same feature as the factory '62 seats.

 

The first CJ-5 had the flat cushion buckets like this, but there was an optional 60/40 (or 2/3-1/3) bench front seat as well. IIRC the 40% side flips forward, and may be the same as the flat cushiop bucket seat. These are not 60/40 seats.

Could be that the first CJ seats were the same frames and cushions as the M38A1 seats, but I thought they had black vinyl covers from the factory. The M38A1 had OD canvas, like this.

 

No. The military seats are much smaller.

They are however interchangeable, I believe, as far as mounting is concerned

 

As mentioned previously, the seats pictured are not original to a CJ5. Your seats have "pans" as a backing that were used with the military and possibly some early flat fender models.
Your '62 would have originally had tube-frames with tied coil springs and batting, covered with vinyl. Most CJs of your vintage came with separate buckets, but the split bench (60/40) were optional.

Thanks for the quick and insightful replies! I'm new here but I'm quickly realizing that this is a well informed and helpful community.
I may give Beachwood a call with measurements of the bases and backs. Considering that they make the covers for all of the early Jeeps, they could probably quickly identify what I have and the correct replacement canvas.

 

Ended up contacting Dave at WeeBee Webbing/ODcloth.com with some pics of my seats and frames. He said that my seat frames are the norm for M38, M38A1 and CJ2A, CJ3A, CJ3B, so I ordered a set of covers. Very reasonable.
Nice quality and workmanship. They're sticklers for the military spec materials, patterns and treatment. The treatment on the OD duck fabric has a unique smell to it that I'm starting to get used to. The interior of my Jeep will have that "MB smell" for the next several months I suspect.
Anyway it's not perfect, but a vast improvement over my old torn seats:
