The instructions are correct. What they don't tell you is that sometimes it takes a lot of force to move it back. I use my foot and sometimes have to brace my back on the back of the front seat to get enough pressure. The procedure is to push on the very bottom of the seat about 2" from either end (do one side then the other) straight back about 2" then push up. The seat frame is sitting in a U-shaped hook that the open end of the U is facing rearward.
I just pulled my rear seat out and it really helped to take a flashlight and look where the hooks are and push right at those spots. I did one side first and then the other. (If the the 67 is like a 72 there are 2 hooks) Prior to looking where the hooks were, I tried to push the whole seat back at once from the center and I was getting nowhere.
I used a flat prybar with a notched end (like what you use to pry out nails), and stuck it under the seat. That way, I could push the wire only, and the notch kept it from slipping off the wire. While pushing it in, I yanked the seat and it came right up. Like Autoengineer said, pushing the whole seat won't do any good.
PITA to get out. Once I removed it, I took a file and ground down the leading edge of the 'hook' portion on the floor pan so that the seat bottom won't have to be pushed back as far next time. It's a much easier job now
Fortunately, they left a slot in the front where you can see the hook, so you can push on the wire (I guess they used some kind of tool at the factory). Mine was really tight, there was no way to move the seat back at all, pushing directly on the wire was the only way I could do it. Couldn't even snap it back without doing that. At least it won't come loose by itself, like it used to do in my Camaro.
Trimming the hooks would be a good idea, should make it easier to snap it back as well. Should have done that... well, hopefully I won't have to remove it again anytime soon.
