Agreed. I wouldn't even build a new landing pad. I'd just cut in a flat section. 5 minutes per side with an angle grinder to cut in a flat section for the radius arm mounts to lay flat against, a rectangular section of 3/16" plate, burn it in, blend it back (if you want), and bob's your uncle.For the arm mount on the hump. Couldn't you just build a flat section under the frame hump. Just to make it flat? Seems like it would work and also be less fab work. Just an idea.
