Hi Glenn,
We didn't build our teardrop but when we looked into it we looked up Amherst Welding (Amherst, MA). If I remember correctly they can order the aluminum for you. There are less of us in the NE with teardrops. When we bought ours in VT last week. We were told that the first teardrop dealer out here was in CT. Welcome and I think our numbers are slowly growing. The day we bought ours, two others did too. I think we were all from MA. They sold a T@B to someone from CT too that weekend.
