I kept removing parts by drilling out the spot welds and using a wood chisel to separate the parts.  I kept all the parts so I can get measurements from them if needed.  I also took some measurements to use for installation.  

The bar over the door space is what I used for making measurements and what I will use for reference later.

The outer sills came off first.

Then the door jambs.

Next was the inner sill.

Now I have to make some parts or get new ones.
