You may get lucky searching around. I found a local marina that was selling off a bunch of junk boats. One was a few years newer but same make/model as mine. I grabbed the bow rail (mine was bent from a previous owner) cockpit seating, aft rail, mooring cover, Bimini top and some other hardware. Wish I had more time to snag the sliding cabin door, hatches and other model specific items.
If you don’t get that lucky, expect to pay a fair amount to have that setup made.
