I think I am going to need to change out the entire floor, each section has issues or bad previous repairs (epoxy anyone)..anyway, I dont think this section is included in the one piece floor, is it the "rear floor extension" ?

The screwdriver shows the area in question, it looks like a jack went through and it ripped. The drivers side is rusted where it connects to the wheel house and a bit into the transition pan, so I will also need to repair the edge of the transition and possibly section in the inner wheel house.

 

OK, now that I have gone back and looked at a pic 2+2 posted I think that section IS included on the one piece pan, but the curved section in front of it is not?

 

I believe the piece in front that is not included with the pan is the rear torque box.

 

I see that now, I think I like this article.

 

I will also need to change my frame extensions and I wonder if it is OK to remove them while the floor is out of the car provided I have support under the rockers? It would make the job MUCH easier!

 

In this picture they are sliding the full pan through the door opening...has anyone here done this?
I really dont want to take out the glass.

 

The full floor is most easily installed from underneath. You must remove the exhaust system and driveshaft, etc. On a car getting a full floor, some or all of that is already off, anyway.

The floor in that photo has been cut down. Kinda defeats the purpose of getting a one piece floor.

 

 

I dont know, it comes up to the seam?

Here is another pic from the article in question.

 

If you're going through all this work take the glass out. I was surprised how much rust I had under the seals.
