Hey guys its finally warming up in ct and i bought floor pans in the winter so im just waiting for a good day to put them in. I have some questions

what is the best way to keep the car from shifting or becoming tweaked when i take the old floor out i plan on doing one side at a time. easier way to ask how can i keep the shape with out messing up the uni body shape,

For the shape can i just leave the car on the ground with all four tires or will this cause a issue.?

When i fit the floor should i make the exact fit to what i took out or should i weld a little higher?

Basically what do you recommend to do this repair?

 

It will not affect the shape of the car by taking out the floor pan, even both sides at once. Butt welding a floor pan would be pretty hard but could be done. It is much easier to lap weld them in. The side have a lip on them where you can punch some hole every few inches and through weld it like the factory did with spot welds. Leave as little overlap a possible when fitting them but be sure not to cut them short.

 

The replacements should have sufficient overlap but make sure you seat the inner edge to the frame. Set the seat base on it before you commit to anything other than an occasional tack weld. If the bases aren't level, your seats will lean towards the doors.

 

I have done "partial" floors, and "full" floors, and I'll never do it in pieces again.

The one piece OE style floor has a few faults, but is arguably less work, and better-looking results than doing it piecemeal.

 

If you are doing front patches and not the whole thing then you will want it on jack stands. I put them under the rear axle tubes and under the front frame rails near where the wheels are so the car sits the same as when its on the wheels. Keep the opposite door closed if possible and pull as much weight out of the car as you can. Welding sparks go all over in there, and you dont want a hundred holes in your rear seat or the door panels.

I did a full floor on the Mustang too, and partials on the GTO Im doing right now. One thing about the full floor is you need some way to get it inside the car. I stuffed mine through the windshield, and yeah it was a bare shell when I did it. Maybe 2+2 knows of another way to get one in, but mine wasnt going in any other way. The partials are LOTS more work, but you get good welding and trimming practice. Try not to overlap them if you can help it unless you plan to weld both sides or tri the excess after you have them finish welded. If you figure out how to trim the left overs without screwing up the new pans let me know.

 

haha ok my car is bare the doors are off and i probably should have just gotten the one piece but im leaving the trans tunnel.

Thanks
