Installing floors

[wirenut]

I have a 71 duster 340 outer body is perfect needs floors. I am capable and have the tools. Just need some guidence.
How, or should I make any preparations, structuraly before I actualy remove the floors. Right now the car is complete, all body parts are still installed. The car will be disassembled at some point. The car will get frame connectors most likley home made. I do have a rotisserie as well.
One thought I had was to install the connectors before I do anything else, then disassemble, drop the k-member, rear suspention. I am not stripping the car to bare metal as any plastic work done was done 30 years ago and is still perfect, although I want to strip off the current yellow paint and repaint the original black. I am not looking to do a full blown resto, lifes to short and the car isnt worth it from a $$$ stand point.
I appreciate any constructive input

i did mine one side at a time. i didnt use and bracing. once i was done replacing my two front floor pans all gaps looked the same and doors still shut the same. if you are going to replace the whole floor at once i would tac weld some supports across the door openings.

were doing a floor job on my dads 74 duster right now, we have almost all of the floor out of the duster and currently cutting the new floor section out of a dart sport many people will tell you to brace the car a such but we did not nor have we ever when doing floors, we used a Blair cutting tool to remove the spot welds and are going to place sub from connectors into the car before we lay the new floor down, remember if your not doing a in show room detail car no one is ever going to see the floors so if you FUDGE somthing up who cares weld it and make it safe good luck

As long as the torsion bar anchor and rockers are good you don't need to cross brace it and yeah i would fit and tack the connectors before it's less screwing around when you install your new pan.

Kinda what I thought. The floors arent even that bad just perforated enough to make replacement make sense. All the critical points are solid
Thanks for the advice.
