I personally have no clue but I've had multiple shop owners, one in the family tell me not to do a patch job, that it wouldn't last as long as putting on an entire new floor. I already have a rust free full floor lying around. You know the old saying of doing it right the first time, then you won't need to fix it later on. I'm getting as many opinions as possible before I start to shred it apart. I don't mind putting a lot of time and money into this car, I'm not looking to flip it for a profit. You don't want to know how much I payed for it.
I bet that the shops that say not to do a "patch job" are using that term as any scenario where you put Bondo on top of rust. There's nothing wrong with replacing just part of a panel of it is done well. Just because you purchase an entire panel does not mean you have to use it.
Looking at your floors, it is likely that you will decide it makes most sense to replace the entire floor. Hopefully your rockers are a different story. And I don't think you want to cut out more than you need to (initially) as this is a unibody construction car.
If you just want this thing to be absolutely perfect with nearly impossible to find welds, then go for the whole floor.
But... Take note that the floor pans you buy are the left floor or the right floor. They don't include the trans tunnel. As I read this, it seems to me that you might be thinking that you'd be replacing the trans tunnel, and I hope that's not the case.
Floors should be easy to replace, but I think that rockers can be more challenging. I think that at least with the rockers, you might try to only replace what you have to. You can determine what you have to replace by chipping away at that rust until you find solid weld-able metal.
I will be interested in seeing what happens here. I've been in similar shoes, bought the new floor, rocker end caps, replacement trunk pan, fender sections, etc., all taking me probably more than a year to acquire the parts, but still driving the car. Then it got hit in the side while parked. Still I didn't let it get totaled. THEN I finally found a similar (less rusty) car I wanted much more and just sold it. The new owner Bondo'd it all up and had no interest in the metal panels I bought for the car.
