I am getting ready to replace the floors on my 66 coupe and was wondering if anyone hasused the one piece floor? Anything I should pay special attention to?

The one I amthinking aboutis fromNPD (part number 011135-1A). It's suppose to be a thicker gauge steel and made in the US.

 

I like the made in USA part. The floor pan is the structure of the car. In order to cut the entire floor out, you will have to support the entire car so that it does not move. Could end up with a tri-pod! Unless your tunnel is bad, the individual pans would be easier, one side at a time. Holding it in position is still a concern.

 

I have never used the 1 piece as its easier to do the individual pans themselves and you will not have anywhere near the problems with keeping the car lined up properly.If I were you I would do one pan at a time as long as the tunnel section is in good shape.If you have never done it and try the 1 piece floor you could end up with a massive disaster!! Good Luck!![8D]

 

I agree. I replaced nearly my entire floor, but peice by peice. The thought of ripping out the entire floor in a uni-body car is haunting. I think you need some experience before you make that your 1st go at it. If the tunnel is in good shape, go with the individual peices, or if you want the 1 peice installed, have it done professionally. OR, find someone with experience and have them help you.You want to have fun with the car, notthe carhave fun with you.

One side at a time.

 

I felt that doing the one piece was the way to go, so I went for it. I'd never done it before, so it was a little scary.. Structurally, you'll be fine as long as you don't go beyond the firewall seam in the front. If you do, it will begin to sag...trust me...that's what happened. One small detail about the one piece floor that kinda screwed me, was the section behind the rear torqueboxes. If you notice the 1 pc pans for convertibles, they have the "eyebrow" for the parking brake cable, where the one for the coupe and fastback do not. If you're going to keep your stock configuration for parking brakes, you'll need to cut this section out and weld in the patch panels offered for repair of this area. They have the eyebrow stamped in it. I went with a 9" Versailles rear, so the parking brake cable was not a big issue for me. All that being said, I feel the one piece floor is worth the effort, and if you remove only what you have to to replace it, you'll be fine. One more point.... I had to put the pan through my windshield opening to get it in the car..! check the pics out below...
