need some roof replacement techniques

Here are some pictures of the roof skin I put on my Mustang. I would suggest just doing the skin. You can punch holes for welding or do as I did and use a large panel adhesive. I actually prefer the adhesive to welding as you can cover all of the bare metal with the adhesive and it is corrosion resistant. Also sparks and interior can be a problem unless you are willing to remove the entire interior.
