Thanks jgr. I just wasn't sure on far to assemble the door for checking gaps. Here is a picture of the order I did things in. As you can see I did brace the "A" pillar to make sure it did not sag down when I cut the floor and kick panel out. Nice thing was my son in-law was here to help. He went to automotive fab school so he was a big help to make sure everything I was doing made sense.
I did have to modify the kick panel some to get it to go but not much. The "A" pillar patch panel was a different story. Nothing really matched up well so I had to a lot cutting and adding material to get it to fit on the cab.
Now on to the inner/outer rockers and the cab corner
