No one makes a set specifically for the Lindbergh Fletcher. I wrote an extensive article on correcting this kit, it can be found in the features section.

The model is large enough that you can actually rig the railings properly. You can probably get away with using 1:100 or 1:96 scale stanchions and setting them a bit deeper into the deck.
