Fifth Wheel Ladder Replacement

Well tomorrow I am gonna be on the phone with Tweety's and etrailer to start with on the subject.

i trashed my ladder and need a replacement. Prob/challenge is to get a ladder that has the stand offs with a round base. i want to cover the same holes/places in the back of the camper. The diagrams that i am looking at seen to have a rectangular stand off anchor and or i cannot tell by reviewing the add.

Anyone done this and can steer me to the right replacement?

thanx
