I just so happen to drive my wagon, today – so I went out a too few pictures.
Unlatched and seat forward about 20 degrees. The floor pan/trunk pan is the same as sedans.
Open a bit more.
Just before seat latches.
Latched.
rear view (ignore the poor mans carpet protector I'm using).
I’m 90% sure the seat bottom is the same (wagon, sedan or coupe). The seat back is not.
I’ve not compared them, but was told the wagon seat back is the same as what is used on 2-doors that also use fold down seats (but that is not confirmed).
There is one seat button (top and center) that controls two different latches.
The seat folded down does not sit flat – because of the seat bottom (foam/spring) compression. You put a little weight on it and the floor will be almost level.
In this state (as pictured), it is a bit higher in front than the rear half.
The complaint I do have about the F & M-body wagons is carpet (not staying on/attached) as well as a huge place to lose things in the cavity behind rear seat bottom.
Then again, that spot might be a great place to hide things (maybe).
In my case, it appears to be hiding trash from my kids.
To answer your questions:
- I’m not sure I understand. The basic shell is the same from ’76 until end of production (’81), with a couple of exceptions:
The tailgate/taillights are different on some M-bodies (the other M’s are the same as all F’s).
’80 and up fenders (F & M) are the same – but different from ’76-79 F-body.
Some M-body rear doors have some cosmetic differences (much like how 5th Ave rear doors are cosmetically different from other M-bodies are.
If you are looking for a wagon, an M-body might be a better choice – but I will say they are a LOT harder to find.
- Not sure about weight of the back upper seat - twenty-five pounds, maybe. I don’t recall having one out of the car, before.
- See above.
If I found a good chassis but car needed interior redone in it – I might consider changing dash over to M-body and install 5th Ave seats into it – like what a member or two here has done.
