I would get the floor supports and floor in place first before tackling the cowl itself. Before you weld the floor/rocker panel (the one across the bottom of the door opening) in place to the hinge pillar, double and triple check the horizontal dimensions of the door opening and the height of the floor reference to the hinge bolts (I believe you can get those dimensions from the FAM - look at Section 1, Sheet 1.07 and Sheets 63.01 and 63..02.) I see that you have the cab braced, which is definitely a good thing.
Thanks for replying, I recall you were most helpful the last time I asked questions. If I can get ONE panel in place this weekend I will be happy...it is progress. I spent some time sitting on a stool staring at the truck and think I have a plan. The floor is not level BUT that is when measured towards the front. You can see from the shot of the passenger side that the floor has risen sharply near the front mount. I guess the cab has sunk in that corner causing the floor to rise, with respect to the more rearward floor which IS still level all the way across.
So, I have a decent reference in that the floor is level near to the seat riser. I can hopefully therefore install the driver's side floor pan, keeping it level (at the rear) left to right, across to the passenger side, and front/rear to the B pillar. The grooved contours in the floor pan allow me to gauge how far forward it needs to be. I will ensure the groove @1-2 inches in front of the seat riser blends well, from the new panel to the original part in the center of the cab. Hopefully that is easy to visualize. Once I have the floor panel in place I should be able to lift the cab of of the frame and insert the floor support which includes the front cab mount.
It seems the next best step is to get the floor panel linked to the firewall, thus allowing the installation of the parking brake bracket, which I can in turn use to help me locate the outer rocker panel. Once the rocker is in place I can turn my attention to the inner/outer cowl, and finally the rear corner.
I know the door 'hole' is critical but at present the A pillar which includes the door hinges is flapping in the wind so as soon as I hang a door on it it droops. I guess I can move it ot the right location using measurements, do a couple of tacks to hold it and then mount the door...
