need headliner help

Bill, when I did the Valiant in mine it was 5 Bows. I ordered mine from E-bay. I watched the same exact video, John posted. My sail panels on mine where ruined. I had to make new ones out of 1/8 particle board. When I did mine I also installed sound deadner to the roof (silver bubble).BTW these cars are easier with the Front and Back windows out. Due to the curve of the back window. Hope the helps. Use a heat gun also, just make sure to keep moving it. Mine came out Awesome.
