Shaun, since I replaced my front bed core, I asked FR to provide one that was already setup for the new style latch, bought the latches and matching mating arms, and lock sets. The only material I supplied was the aluminum backing plates (stock cut to size), the SS hardware, and some vinyl trim to use as a spacer (not sure I even needed that). FR folks indicated new campers were designed with a stronger bracing for these latches, but older models may not hold. THis has worked fine, and you cannot see the backing plates with the curtains to the sides.
