So to get the accord upper half of the back seat I did the following:
1. Remove the stock seat
-the side bolsters have a 10mm that can be reached with an extension (look in between the upper & lower haves near the seat belt)
-remove the main portion of the upper half (unbolt the hinges from the body of the car)
2. Modify the civic hinges and the accord hinges to fit together
-drill out the center of the accord hinge so that it is separated in 2 haves (the half that bolts to the seat & the half that bolted to the accord body)
-take the bolt that held the civic hinge to the seat and line it up with the hole in the accord hinge)
3. Remove the latch on the accord seat
-it doesn't line up with the civic body and isnt really needed
-Use a hack saw or anything really
4. Shape the accord side bolsers (optional)
- pull back the fabric and shape it so that it fits near in better
5. Install the accord seat
-the side bolsters will line up with the slots and bolt holes w a little bit of bending
-the center should line up and the hinges will bolt in
Sorry i dont have any pics but i will be making a full DIY when i get the time to go to the junk yard again. I plan on doing a full DC2 front, accord back leather conversion.
Here are some pics of how it looks installed in my sedan
