Buoymaker, thanks for the pictures and the information. In your pictures it shows the floor panels done before the outer cowl is worked on which makes sense but it also appears that you did not need to install inner cowl panels. From what I have learned the floor edge is sandwiched between the the inner cowl and the rocker so I suspect that I need to remove both the inner cowl (at least the flange area) as well as the floor to fit the new floor panel in place unless I trim off the flange on the floor panel and butt it up against the inner cowl. I am not sure about trimming off the flange because it adds a lot of stiffness to the panel. My body does not have a driver's side vent that I am aware of but does have a passenger vent (air intake I believe for the heater I do not have).
Klhansen, my passenger side panel stops short of the top of the top of the vent opening and the driver's side is similar height but they are painted black. My panels were from Classic Parts part numbers 44-111 and 44-114. Also thanks for the insight regarding the running board fasteners, not sure why I didn't think about just tightening to break them. As long as I can get decent socket engagement that should work. Getting a cutoff wheel up inside the support channel to cut them seems like it would be a challenge but I do have a Dremel with cut off wheels that may fit if I need to cut some. I am sure I will need new fasteners regardless of how I get the old ones removed. Unfortunately it is cold and predicted to stay that way for at least the next week so and therefore activity is limited to working on patching/repairing fenders, etc. that I can easily carry to the other (heated) shop.
