Hey guys. Im looking into replacing the entire floor pan of my 66 coupe. I had a few questions regarding the project:

1. WillI have to remove the body from the frame (and if so, it is bolted on and not welded, correct?)

2. Is it better to buy a one piece floor pan (keep in mind I would PREFER to leave the body on the frame) or should I buy each floor piece separate and weld them together

3. Finally any advice before I begin?

Thanks, you guys have come through for me many times and I appreciate everything.

 

Ummm....dude.....frame?
Unibody construction....
Floorpan = Frame

From what I understand...if you remove the whole pan..you have to fixture the car...so it dosnt look like a banana when your done.

 

I did the full floorpan on my car... First off its a major pain in the rear.
I would HIGHLY recommend doing the halves.
Get about 8 jack stands and support the car completely. In the front, rear, and sides. Also remove the engine tranny etc so the car isn't weighted down.

 

hity645 is a wise man. There is no frame on these unit body cars. You replace parts in small pieces so the car doesn't fold in half.

 

Just out of curiosity why are you replacing your floor pans? i assume rust but we know what assuming leads to.

 

Man if you do it, please document and take pics (time permitting, of course). This is a project I have been really wondering about. If it's too big of an obstacle to hurdle for a first-timer, I'd like to know so I don't buy one with an already bad floor. GOOD LUCK!

 

We made the mistake of not supporting the car with jacks and leaving the front and rear end on. With the design of the car, the weight was pushing down on the front end which in turn pushed the tires out which gradually spread the car apartt to leave a 1/4 gap around the floor, it shrunk once we removed everything and go it on jack stands but there are still areas where there is a gap which Im not happy about. I wanted to do the one pieces, or even the halves and leave the tranny hump in place. Seriously unless the tranny hump is irriating you do the halves not a full piece.

 

Afull floor pan would seem to be more work anyway if you think about it (fitting with the rocker panels, trunk etc.) Just incase you didnt quite grasp what Stevetra meant the frame is basically part of the floor (welded to each other)and it doesnt extend from the front to the rear(just2 frame rails in from and 2 in back). Since its unibody you cant pull the floor away from the frame like you would on other cars.

 

Hey Soup,I have the same floor as you. If I get mine in before you,I'll take lots of pics and post them for you to see.

 

Thanks for the great information. I considered getting a full pan before this thread. My tunnel is still solid so I'll be going with halves. I definately won't get to my project before you guys so please take pictures.
