if its like my 1990 Champion Lasalle, the side molding is 1 1/2" wide and has a center filler strip that snaps in. Behind the filler strip is where all the screws are that connect it to the body where the upper panels meet the bottom galvanized panels. The automotive type stick on will not do the trick if thats the case. http://www.factoryrvsurplus.com/products.php?product_id=2070
