I aired a 2002 hi lo bronze 23lx. Got the hydraulic unsiezed, as I went to manually raise it the front wouldn't raise. The sides were so rotted it pulled the steal tubing which now I'm in process of replacing the whole walls. My question is, where are the guide blocks located on this thing? I've tore out one whole side wall and there's no guides at all. Should I be able to see them anywhere along the side wall or are they located in the front and back? Thanks for any help, pictures,and pointers. Ill take pictures as I go along and progress
