anyone can help me with how I could frame this section of the van so i can attach a wall to it? This is the rear of a 1995 G20 van. The box is a rear AC/heater unit that I would like to keep. To the left of the heater is my only rib I can attach the wall too. I do not have any ribs to the right of the heater. I would like to add a wall that would start at the left rib and end at the rear door wall and cover the ac unit, maybe have some little storage if it doesn’t complicate the framing too much. Would be very happy to hear some suggestions from more experienced folks, this is the only part blocking me from starting the walls. Thanks 🙏
