I haven't gotten into this part of the project yet. I don't THINK I need to brace the door openings since the portion of the rocker that needs help is in front of the door frame. BUT I was planning on bracing the doors from the hinge mounts to the latch side anyway. Probably a brace from drivers to passenger side as well.
For the A-pillars, do you mean from side to side or front to back? Or both? Tack welding the braces?
You should brace no matter what. Measure the door openings before removing the doors in multiple places, especially if replacing cowl panels and cab corners or you’ll wind up grinding the door edges. (Don’t ask how I know that. 😉) On the A-pillars I used the hinge bolts for side to side. You could also tack weld.
