When the top is lowered, it should rest on the OUTRIGGERS. Nothing on the top half should rest on anything on the lower half on the inside.
The outriggers are those four square tubes attached to the frame on the outside. Many units were also designed to rest on the "A" frame and rear bumper. When I purchased my first Hi Lo, there were no rubber bumpers on those outriggers. So I bought hockey pucks, and screwed them in place. Even on my latest Hi Lo I use them, just to give myself a little more room.
I've heard of folks breaking light fixtures because of cable slack and the top coming down TOO far. The hockey puck bumpers prevent this. Even if your going to replace those cables, you should become familiar with cable adjustments, because those new cables ARE going to stretch pretty quickly.
