91 Ranger Driver-Side Cab Body Rot Repair

[BigBoy]

Looking for advice or structural repair resources on how much of this cab I can replace without causing any structural issues. I got the replacement panel from a scrap yard off an 84 Ranger, mine is a 91. Besides some seat mounting holes I don't think they are much different and this is the best I am probably going to find.

I would like to make this replacement panel extend past each frame cab mount so basically the whole lower section of the blue panel – rocker/floor pan/cab corner/bottom corners of the hinge pillar and B pillar. Looks like my rot goes just past where the floor pan seams to the firewall so I am thinking going a bit into the fire wall as well. Any tips or suggestions??

Couldn't find the "help" threads, my apologies if posted in the wrong place.

I like body work more than I like swapping mechanicals... I did see a good cab a couple hours away for $700 but thats crazy to me if I can replace this without any structural issues.
