66 mustang floor pans

Well after letting it sit in the garage for a few years I have decided to dive into the restoration of this car again. Right now I am tearing out the old floor pans, etc. My question is, when I put in the new "toe boards", is it best to butt joint these or can you overlap just a little when welding in. Also, does anyone have any pros or cons to putting in the complete floor pan assembly or doing each side separately? Thanks in advance for your help.

Good question, i just bought a 1968 Mustang coupe that is in need of floor pans. Maybe posting this in the Kevin Tetz section would get an anwser from a good sorce.

I choose to do them separately because my Falcon is a convert. I did a slight overlap spot welding and then cleaning up each spot. Sprayed some anti rust primer and later will fill seams top and bottom. If you do the entire floor board at one time prevent sagging of frame/car by welding bars across you door openings. Removing doors makes job easier. I've heard of others having sagging when you lose the structural strength of the floor.

Manufacturers now offer full, one-piece floor pans for Mustangs. They didn't offer these back in '87, so I wound up getting left and right, full length floor pans. Fortunately, I didn't install them yet and am going to use the one piece. The one piece floor pans solve the problem of joints at the transmission tunnel and will wind up saving a lot of time. And yes, like you I am finally getting back to business on my '66.

From the factory the floor pan overlaps (on top) the toeboards and are spot welded. If you want to replicate the factory look, you can do the same over lap and put plug welds every couple of inches.

I actually butt welded mine all the way around where it attached to the firewall, and plug welded at the floor pan seam as mentioned above.

Here is a link to my floor pan / toe board project. Note the project continues over a period of 2-3 months with links over on the right side.
