I got after replacing our streetside lower rear panel on our 1959
Ambassador this weekend. That was fun! We got the panel from airparts, cut it, to fit and took a video from the inside of getting it reinstalled. The hardest part was getting everything straight and tacked in. We're lucky because this panel is the underside of both the top rear and the mid rear panel so we're able to not have as exact cuts as it ties in behind those panels. We used 2024 T3 AlClad .032 aluminum sheeting. By the way, the people at Airparts are awesome to deal with!
