I ordered and recieved a new ladder directly from Ranger. Can you guys help me with the exact location that it needs to be mounted? A few pictures. My concern is there are several weld marks where the factory installed bracing on the back side of the outer skin. I just want to make sure when I drill my holes I’m missing these braces. I only have 2 factory screws. The others fell out of a crack in the box during shipping. Instead of using self taping screws, I think I’m going to tap and thread the holes for SS screws. Then lock-tight the screws. Thank you for your suggestions and help. Allen
