Get your self a factory assembly manual, Do a search on e-bay for 65 el camino under parts and assories. All the trim is either bolts or clips. None of it is really difficult to remove. You will find all the parts you need on e-bay, and the el camino store. Factory originals are the best. Your trim is the same for the bed, back and front window and drip rails for 65, 66, and 67 el caminos. The hardest pieces to remove is the drip over the door and the door trim which is friction fit. Have fun and keep your frustration level low.
