I recently deleted the sunroof on my '81 project. It took a
lot of work!
My process involved cutting and removing the entire stock sunroof assembly, gutting the stock sunroof panel leaving just the panel, trimming the sunroof hole in the roof, cutting filler metal to fill the gap between the sunroof hole and sunroof panel, clamping everything in place and adjusting for the right contours, Mig'ing the corners, and epoxying the seam and filler metal.
Then I had to sand sand sand sand sand and sand some more on the roof to get the roof contour to look correct.
It was a lot of work but I'm glad I got it (mostly) done.
