Before you even consider doing this there are 2 sites you need to visit. Emery Stora\'s Middle Age Spread paper located at http://www.california.com/~eagle/spread.html and Richard Waters site http://www.palmbeachgmc.com/middle_age.html . Also Bumble has an album at http://www.gmcmhphotos.com/photos/showgallery.php?cat=3748 . Now guys you have to remember I have an advantage here because I have the headliner and refrigerator out. I used a brace at the top of the refer cabinet and proped my roof up. I had some roof sag and the ribs were to low causing the headliner boards to be to tight (not enough space between the cabinet and the rib. So I setup the top of the cabinet before I squeezed. You can tell if you have this problem by pushing on the headliner along the cabinet wall. If it moves up and down your OK. You need to check the rib that is directly above the generator switch. Of course I suppose you could ignore that and deal with it later. The important brace is the one that pushes the cabinet to the wall at the top.
