What is the best way to replace floor pans. And can you do it with the car on the ground, and what might be some things I should do while i am repairing the floor? Can anybody tell me exactly how to do this and what I should watch out for or beware of while I'm doing this?

 

There is a ton of info on the web about this repair, such as: http://www.mustangmonthly.com/howto/...ace/index.html

Check on youtube also and you will find a number of videos showing the process. Hot Rod has a series of videos out and one of them is all about sheet metal work and they show how to replace floorpans in a classic Chevelle, which is generally pretty much the same process as for the Mustang.

Try to narrow your questions down. I doubt that it is within the scope of a forum thread to tell you 'exactly how to do it'. And there are a lot of opinions out there about the 'best way'. And there are a ton of things you need to watch out for. Try to break your requests about this project into more bite sized pieces and you will get more complete answers to help you out. Post some pictures too, for instance show us the condition of your floors now and you might get suggestions more specific to your needs. This is a great place for information, you just need to be aware that a lot of people have done a lot of repairs in a lot of different ways. You will be doing yourself a big favor by asking more specific questions. Just my personal observation.

As to the specific question you asked, the job can be done with the car on its tires (which, I assume, is what you meant by 'on the ground'). Many will suggest that it is better done on 4 to 6 jackstands, as this way gives you the ability to level the car (suspensions are rarely level) which makes sense when you realize that the floorpans play an important structural part and you want to be sure that everything is square when you start welding. That ceratinly makes sense.

Good luck with the project!

 

Thank you, and that is what I meant by on the ground. lol, i will try to be more specific. I am trying to find a camera to borrow to show the current Condition of the car.

 

This is an extreme example, due to how bad the car was, but you get the idea.

 

I'm in the same boat. The passenger and both rear pans need replaced, along with the sections the rear seat. I'm thinking about getting the passenger side full section, drivers side passenger section and the two sections under the rear seat. There will be a lot of cutting and welding. With hopes of not twisting the body. I thought about supporting the whole car with jack stands. What do you all think about that idea.

 

Jack stands, with of course some means of leveling them, with spacers or sheets of thin plywood. Use a laser from the home repair supplier to level it.

Don't piece the floor together, if the whole thing is shot it'll be less work and better results to use the OE style one-piece floor.
