New one piece floor to wide?

[FlameOut]

I've been attempting to install a new one piece floor into my 72. I first braced everything to assure there would be no shifting of any part of the cab.

I got the old floor out and everything cleaned up, but noticed my new floor is 66 1/2" wide, but my opening between the kick panels is only 65"

I expected a little difficultly and possibly some trimming, but an 1-1/2" is quite a bit. Is it possible my old floor was so rusted that there was already shifting of the cab before I braced it? I'm a little tempted to remove the bracing and spread the door pillars to get the floor to fit, but that would probably open up a whole new can of worms

Could someone measure their distance between the kick panels, right at floor level and let me know what you have? I already installed the new front and rear pillar repair panels on the right side, but won't even attempt the left side until the floor is in

I also have a 66" opening at the back of the pan, but new pan is 67" but I am able to get that to fit nicely (centered) because right now there are no cab corners to interfere
