I marked some lines and cut the donor roof. Then I sat it on top of the other roof to mark it. I forgot to mention that I cut the rain gutter and attached it in the rear and the front section of the gutter in the front over the doors. This gave me the front lip position of the front roof section and the rear position of the rear of the donor roof. All that was left was to mark the front section and cut to match the two halves. I would have liked to have had been making my cut on the front roof section more in the middle of the roof where there is the highest peak to the roof but I just didn’t have enough roof. I figured I could compensate with a metal stiffener between the two sections possibly. Regardless I only had two caps to work with. I can see how some people might have used three donor roofs; this roof is loooong.
