Once the fit-up with the panel off the car was good enough, then the hard work of welding it in place and straightening the remaining portions of the original roof began.
Here it is at that about that stage...all the seams are gas welded except for those around the perimeter which were MIG welded since there is no access behind them to planish the weld.
After the welding some final hammer and dolly work brought the two panels into shape and agreement with each other.
In the tradition of the workers on these cars of the past - he included a little graffiti...I am truly amazed by the level of craftsmanship displayed in this roof.
This work was so far over my head (pun intended - I just couldn't resist) that I frankly am in shock. Thanks for following along.
