I was also able to score a really nice double wall top. Due to the construction of the double wall top, they're prone to a lot more issues that the single walls. If you have a 70-72 i would personally go with a single wall top. With the 69's the interior of them were painted body colour. Because the single walls never came with the interior painted body colour, you are kinda forced to go with the double wall when looking for that factory correct appearance.
