Glad to hear you got those corner patches figured out. Car is really coming along nicely.

I have been researching replacing the floor in my '69 Barracuda and came across what I think is a really good video of full floor replacement on a '68 two door satellite:

While waiting for my compressor parts to come, I decided to take another look at the rear deck panel fit.

The right front corner was giving me all the problems and today I found out why.

Here is the left front corner with a straight edge along the end.

Now here is the right front corner:

No cut away at all. I will get the tin snips out and make this corner match the other. My guess is it will fit a whole lot better.

I found out that I didn't need both the inside and outside lower window corners.
If you took the outside corner and trimmed it all down, you would have the inside corner.

Here you can see the inside corner fits perfectly into the outer corner:

So I removed the inside corners and then trimmed the outside corners to fit:

You can see in the above picture that I had to custom fit the inside edge where it buts to the filler panel. The quarter panel in that area had rusted and had to be cut out. I left a little flap on the outside corner patch that I bent to form the round edge.

Had to do the same on the other side as well:

Decided I should replace the trunk floor before installing the rear deck panel.
It was a fight to get the old floor out but cutting it in half just ahead of the cross brace helped.

Still have to clean up the edges. Then I will hammer and dolly everything back in shape, clean and epoxy prime.

Saved the old floor for now. Measured positions of parts I need to transfer to new floor pan.

Are you going to cut the new Pan in half to install ? Or remove the Tail panel go in with 1 solid piece Like I did the Firebird?

Also are you planning on Blasting your inner Frame rails?

Nice work I might add keep it up!

I am going to blast the inside and outside of the rails and surrounding areas, the 2 coats of epoxy.

My thinking is that I can get the pan in there in one piece, which is why I left the rear deck panel off. It gives me more room to angle the pan and hopefully get it in there.

A trial run will be coming in the near future.

The floor pan will "almost" fit but not quite.
I found a website with a guy saying it will fit but look how he installs it:

He removes the rear support brace, which in and of itself is a major job:

Then slides the floor panel through the slot between the floor braces and tail

It's back to the drawing board for me. I will play around with some ideas that aren't quite so time consuming and difficult.

Ok, reading through your floor pan portion of this thread leads me to a serious question.

* With your skills, why wouldn't you just cut that pan up, install it and reweld it in place?

That is still an option but I like to keep as much of the integral strength of the stamped pan as possible.

I am not doubting Jims skills NOT ONE BIT!!!!!

BUT!
Its almost impossible for anyone to cut the pan in half then weld it back together in the car and be impossible not to tell what you did and too purist well.....

I say remove the tail panel for easier install in my opinion then reinstall it, its still a crap load of work & probably a lot more removing the tail because you have to repair the panel to reuse it but worth it in my opinion. My Inner support Brace was shot anyway it was ate up with rust.
I like the idea of what that guy did but it looks like he may have tweaked the frame rails in the process pulling them down so much. BUT maybe it wasn't all that hard to get them back into position I do not know? could be the way to go with that body ? I am no way against a good short cut that works! and doesn't harm stuff. Its just sheetmeatal and spot welds lol !

Started media blasting today to remove rust from frame rails and supports.

Some progress made:

More to do but it was hot and humid so I got tired quickly.

I am getting the worst of it the first time through. Will go back over everything to be sure I got all the rust out.
