I'm hoping someone can help with installation of a new convertible top boot for my 69 RR. I bought it from Year One but the hardware packet that came with it was from Legendary. I know I have to attach the metal snaps on each side but I can't see how the front leading edge fastens to the crossover bar along the back seat. It appears to be missing clips or fasteners along the front edge. I've attached a photo showing underneath. Am I missing something?
