This clear plate assembles to the bottom of the ship. It becomes the structural component of the assembly, takes ball impact from below, and supports the ship when a ball hits from the top.
Assemble the locknuts to the existing screws, so that the plate sits level with the bottom of the molding. Leave the ship a little bit of slack. Then, tighten the washer locknuts hard against the wire and the plate.
The final assembly is much more rigid than the original. The plate is cut to precisely match the contours of the original Williams part, but should work with repros.
The plate is shown assembled to the ship and wire in the pictue. The tight cut to the outline makes it hard to see. Sorry, but all you get is the plate and nuts, you'll need your own ship, screws, and wire.
And for those who want to experiment, we'll make you one in fluorescent red/orange.
