No but I could go measure them at the weekend for you, I would change the design in 3 ways, Firstly as I was going to but as somebody finished them for me they didn't, I would put the hinge right along the back edge, I also just used a long piano hinge you can now get waterproof hinges, they use them on the teardrop caravans. Secondly the lid would have a lip all the way round, again to stop water egress, and finally if I had access to a tig I wouldn't have a frame on the inside I would just weld up the edges.
