I finished welding in the tail panel on my '70 today. I used a Goodmark piece and was very impressed with the fit. The hard part was getting the old one out. It's spot welded inside the upper quarter panel,as well as many other places. I took my time drilling out the spot welds, and carefully air chiseling to separate. Challenging, but rewarding in the end.
